Deloreans.

They have exponentially gone up in value from 2008. Used to be avg. $19k, but now you cant find one for under $30k in good condition. So, that is what I would invest in. SIt on it for maybe 10-15 years and have a pretty good sum of cash waiting for you. And it would be fun to drive it around while you wait for those years to tick by...

Also, Ferrari 360 Challenge Stradales have gone up. It's absolutely astounding that a car only 10 years old has fluctuated so much in value. The car was originally over $200,000USD, but they went down in around 2010 to nearly 100. Now they are back up to $185k and climbing. There were only 1288 made, and several are gone so these are getting pretty exclusive... Just sayin'.

Ford GT
Lamborghini Diablo SE30 / SV
Porsche Carrera GT
Jaguar XJ220
Lamborghini Countach

Maybe 1st gen Gallardo Superleggera and Porsche 911 GT2RS (997) also

Ford GT is the American car to actually go up in value from MSRP in the last 20 years. No joke. This is fact.

And obviously, as stated by some other people, the F40, 300SL, and CGT are fantastic.

But, this is an investment we are talking about. Thats when you start LOW and go to HIGH value. Not high to a just little bit higher. 300SLs are stable at the price as well as F40s. They wont just continue to climb like 250GTOs.

bmw e30 m3 also

gp edition or actual gp race car?

BMW M3 Lime Rock Edition

can't forget that

GT3 RS 4.0. It is the last manual RS Porsche that will ever be built.
