Why "Or Similar" Is the Worst Phrase in Car Rental — and How a Guaranteed Car Rental in Miami Fixes It

Picture it. You've planned the Miami trip for months. You booked a convertible — a real one, top down, the whole reason you're excited to land. You get to the counter after a long flight, and the person behind it gives you the look. The apologetic half-smile. And then the line every traveler dreads:

"Sorry, that's not available right now… but I can put you in something similar."

Our founder Leo heard himself say that line hundreds of times. Before Miami Convertibles existed, he worked the counter at one of the big corporate rental companies, and he watched the same thing happen over and over: excited people, deflated in an instant, their vacation starting with a downgrade. In 2012 he decided to build the company that would never do it. That's where a guaranteed car rental in Miami actually comes from — one person who got tired of breaking the promise.

It's worth sitting with how strange that is. An entire industry built a standard practice around telling paying customers, at the last possible second, that they can't have the thing they paid for. Everyone in it just accepted that as normal. Leo didn't. He'd seen the shoulder-drop too many times to pretend it was fine — and he was convinced that a company that simply kept its word would win, because almost nobody else was even trying to.

What "or similar" really means

When you book a car and the fine print says "or similar," you haven't reserved a car. You've reserved a category. The rental company is promising you something in the same rough bucket — and they decide what that means, at the counter, after you've paid and traveled and have no leverage left.

In practice, "or similar" is how a booked Mustang convertible becomes a sedan with the same number of doors. It's how a Jeep becomes a crossover. It's the industry quietly reserving the right to hand you something you didn't want, and calling it customer service.

When the fine print says "or similar," you haven't booked a car. You've booked a category — and let them decide what that means after you've already paid.

Why rental companies do the switch

It's not personal — it's fleet math. Traditional rental companies optimize for one thing: keeping every vehicle earning. They deliberately overbook popular categories, because a car sitting idle is money lost. When the numbers don't line up on a given day, someone gets the "similar" conversation. Specialty vehicles like convertibles get hit hardest, because the big companies carry very few of them to begin with.

That's the dirty secret behind a lot of cheap convertible listings: the company may not really have the convertible. They have a booking system that lets you reserve one, and a counter script for when they can't deliver. The low headline price gets you in the door. The fine print protects them when the car isn't there.

There's a second layer to it, too. Even when a big company does have convertibles, they're usually a tiny sliver of a massive, generic fleet — a handful of cars spread across an airport operation built around sedans and SUVs. Nobody there specializes in them. Nobody's job is to make sure the convertible experience is right. You're one line item in a spreadsheet optimized for utilization, and utilization doesn't care whether your anniversary trip starts with the car you dreamed about or a beige crossover with the same number of cupholders.

What a guaranteed car rental in Miami actually guarantees

Here's our whole company in one sentence: the car you book is the car you get. When you reserve a Mustang convertible with us, a Mustang convertible is waiting for you. Book a Jeep Wrangler, you drive a Jeep Wrangler. No category games, no counter surprises, no "similar."

We want to be precise about what that guarantee covers, because being straight with people is the entire point. We guarantee the exact model you reserve. The one thing we don't promise is a specific color — colors depend on what's available on the day, and we'd rather tell you that up front than imply something we can't always deliver. So the honest version of our promise is simple: model guaranteed, color based on availability. That's it. No asterisks hiding a downgrade.

The car you book is the car you get. Model guaranteed, color based on availability — and nothing hiding in the fine print.

How we actually keep the promise

A guarantee is only worth anything if the operation behind it can back it up. Ours works because we're built differently from the corporate giants:

●        We specialize. Convertibles and Jeeps are what we do — we're not squeezing a handful of them into a giant generic fleet. We run the largest Mustang convertible fleet in Florida on purpose.

●        We don't overbook categories to "optimize." If it's on the site, we intend to hand you the keys to that model.

●        Paperwork is done before you arrive, and pickup is contactless. No counter line, no upsell ambush at the worst possible moment.

●        The price you see is the price you pay — no mandatory add-ons disguised as required, no insurance pressure sprung on you at pickup.

●        You get real humans on the phone, by email, and on WhatsApp, before and during your trip. Family-owned since 2012 isn't a tagline — it's who answers when you call.

None of that is complicated. It's just the result of building the company around the promise instead of building the promise around the company. When keeping your word is the point rather than an afterthought, "or similar" never has to enter the conversation.

What this means for your trip

The switch at the counter isn't just an inconvenience — it lands at the worst possible moment. You've flown in, you're tired, you've got a hotel check-in and a dinner reservation and people counting on you, and now you're negotiating over a car you thought was settled weeks ago. The leverage is entirely on their side, and they know it. That's the whole reason the fine print exists.

A guaranteed car rental in Miami flips that dynamic before you ever land. When the model is locked, there's nothing to negotiate at pickup — the car is simply there, paperwork already done, keys ready. For a bucket-list tourist who upgraded "just this once," that certainty is the difference between the trip they pictured and an expensive letdown. For a hotel concierge or cruise operator sending a guest our way, it's the difference between a glowing thank-you and a complaint that traces straight back to their recommendation. Certainty isn't a luxury in this business — it's the entire product.

Five questions to ask any car rental company before you book

Whether you rent from us or not, protect your trip. Before you put money down on any convertible in any city, ask:

●        Is the exact model guaranteed, or does the fine print say "or similar"? If it says similar, you don't have that car.

●        What's the total price at pickup — including every fee and any "required" add-on?

●        Do you actually own and carry this vehicle, or are you reselling a category?

●        How do I reach a real person if something goes wrong mid-trip?

●        What happens if the car I booked isn't there? A confident answer tells you everything.

The company that hesitates on the first question is the company that's going to hand you a "similar" car. The one that answers it without blinking is the one worth booking. We built Miami Convertibles to be the second kind — because Leo spent years being the first kind, and knew there was a better way to do this.

BOOK THE CAR. GET THE CAR.

No lines, no hidden fees, no "or similar." Reserve the exact model you want and have it ready and waiting — the way renting should have worked all along.

Frequently Asked Questions

What does "or similar" mean in car rental?

"Or similar" means you've reserved a vehicle category, not a specific car. The rental company promises something in the same rough class and decides what that is at the counter — which is how a booked convertible can become a sedan. It's the fine print that lets companies substitute a different vehicle after you've already paid.

What is a guaranteed car rental?

A guaranteed car rental means the exact model you book is the one you drive — no substitutions and no "or similar" category games. At Miami Convertibles, if you reserve a Mustang convertible, a Mustang convertible is waiting for you. We guarantee the model; the only thing offered on availability is the specific color.

Why do rental companies give you a different car than you booked?

It usually comes down to fleet management. Traditional companies overbook popular categories to keep every vehicle earning, so when demand outpaces supply on a given day, some customers get substituted into a "similar" vehicle. Specialty cars like convertibles are hit hardest because big companies carry very few of them.

How do I make sure I actually get the convertible I book?

Book with a company that guarantees the specific model in writing rather than one whose terms say "or similar." Ask whether they actually own and carry that vehicle, confirm the full price including fees, and make sure you can reach a real person mid-trip. A specialist convertible rental that guarantees the model is your safest bet.

Is Miami Convertibles really family-owned?

Yes — Miami Convertibles has been family-owned since 2012, founded by Leo after years of working the counter at a large corporate rental company. That founder-led, family-run model is why the guarantee holds: real people stand behind every booking, before and during your trip.
