Everyone talks about million-dollar cars that have already skyrocketed in value as great investments. The problem is, these cars are rarely affordable for most people and are incredibly hard to find. At that point, it feels more like the aftermath of an investment opportunity rather than future growth. We want to talk about the cars to invest in now.

That’s why we’ve prepared a list of four underrated 90s cars that are still relatively affordable and could seriously rise in value over the next few years. Some experts have already started mentioning their names — these might be the cars to invest in now.

Audi TT Mk1

The first-generation Audi TT is finally starting to get the appreciation it deserves.

When it launched, the TT looked like nothing else on the road. The minimalist interior, rounded design, and futuristic styling made it feel more like a concept car than a production vehicle.

And yet today, you can still find decent examples for around £5,000.

That feels incredibly cheap for a car that’s become such a recognisable part of 90s automotive culture.

As clean, unmodified examples become harder to find, values could start climbing fast.

Alfa Romeo GTV

Few cars capture 90s Italian character quite like the Alfa Romeo GTV.

The styling still looks stunning today, with sharp lines and unmistakable Alfa personality. It’s the kind of car enthusiasts instantly admire, yet somehow prices remain surprisingly low.

Many examples still trade around £5,000.

That feels almost criminal considering how unique the car is becoming in a world filled with oversized modern crossovers. Beautiful design, analogue driving feel, and growing rarity usually create a strong recipe for future collector value.

Subaru Impreza WRX STI Version 1

Recently, the legendary Subaru Impreza 22B STI exploded in value — with some examples increasing nearly fivefold.

That’s exactly why many enthusiasts believe the early WRX STI models could be next.

The Version 1 STI still sits around £20,000, which suddenly feels affordable compared to where top-tier Japanese performance icons are heading.

Raw turbo power, rally heritage, lightweight chassis, and massive enthusiast demand make this car a serious sleeper investment. Especially while clean Subaru examples still exist.

Lotus Elise

The original Lotus Elise represents something modern cars are slowly losing: simplicity.

It’s lightweight, raw, analogue, and completely focused on driving feel rather than screens or luxury features.

Right now, many examples still hover around £20,000, but cars like this are becoming incredibly rare.

As enthusiasts continue searching for pure driving experiences, the Elise could become one of those cars people look back on and say: “I can’t believe these used to be that cheap.”

Final Thoughts

Car values usually explode after the market finally notices what enthusiasts already knew all along. That’s why the best investments are often the cars nobody’s paying attention to yet.

The 90s produced some of the most unique, analogue, and character-filled machines ever built — and many are still surprisingly affordable today. This is what makes them the perfect cars to invest in now.

The question is: which ones won’t stay affordable for much longer?
