Also anyone that says the F1, 300SL, 250 GTO, Daytona, or anything else like that is missing the point. Those cars have already appreciated to insane levels in the past few years. Others I think will hugely increase in value in the next 10 years are the XJ220, Porsche 993, Boxster Spyder, GT2 RS, V8 Vantage (the '80s one), nice 308/328s, 512 Boxers, and the Countach.

Alfa Romeo 8C
Ford GT

Koenigsegg CC8S- the first (and ugliest IMO) koenigsegg built

Lamborghini Murcielago SV

I thought Porsche was still considering offering manual transmission with the 991 GT3 RS.

Aventador and sls

I have heard otherwise but I may be wrong. Even if they do, the 997.2 RS cars will still probably be a good investment.

Maybe SLR idk

Maybe SLR Stirling Moss.

Koenigsegg. Any of them. They were built to shatter records and beat the Veyron!

The Alfa 8C is also a good investment, as well as the BMW Z8.

The CGT seems a bit too expensive already

The SLS seems to popular and mass produced to go collectible

The Corvette C6 ZR1 will go nowhere but up

As I already said, the Ford GT

The Audi R8 GT, pretty rare, and inexpensive for the performance it brings

Nissan GT-R Nismo is going to be as rare as an R32, R33, and R34 soon

A STOCK Toyota Supra, since most are tuned already, the stock ones will become very rare.

Nissan Skyline R32, 33, and 34

The Ferrari 355 and 348

Maserati 3500, 3400, GT, coupe, gransport, and Cambricorsia models

Those are too expensive already

Hmm I think the 370 Nismo might be a good investment.

Yeah that too

and 90's RX-7's

Also, the NSX is gonna jump soon
