I made a blog post about this a long time ago but I have some additions to my list and we can discuss it here. Post cars that you think will become significantly more valuable in the next 10 to 20 years. Don't say something stupid like the 250 GTO or some other car like that that already costs a fortune. Try to think of a car that hasn't become insanely valuable yet but that will eventually. Some cars that I think are great investments right now is the Diablo SE30, any Countach, Ferrari 308/328, Ferrari 512 BB/BBi, XJ220, Ford GT, Carrera GT, 575 Superamerica, 360 CS, 550 Barchetta, 599 GTO, SLR 722, Boxster Spyder, and the 997 Speedster.

I think the Carrera GT, 512 BB, 599 GTO, Noble M12, XJ220.

I'm going out on a limb and saying the Aston Martin Virage might. They only sold around 1000. But I'm thinking that will be 20-30 years from now if it does become valuable. I also think the Porsche GT2-RS might as well.

Something tells me all of the Mercedes AMG Black Series cars will eventually be worth some good money. The F430 16M, Fisker Karma (eventually), Gallardo Peformante and Supertrofeo, Porsche GT2 and GT3.

Good point with the GT2 RS. I didn't even think about that one but you are totally right.

Porsche 993 (Turbo, Turbo S, GT2, Carrera RS)
599 SA Aperta
512TR
F355
Viper SRT10 ACR

I think some of the older Lamborghinis that aren't worth much yet like the Silhouette and Urraco (I think) will be worth a bit in the future.

Before I read your whole post Andrew I already had Ford GT in my mind.

Jag xj220 sell for around 300k in UK, but Oakfields had a 220 for 129k with fewer than 600 built they are garunteed to rocket in value.

Someone sold an xjr15 for 300k too, I see that becoming a million pound car in the next decade.

I think the Ariel Atom, EB110, Ford GT, Bentley Mulsanne, Morgan Aeromax, Saleen S7, Alfa Romeo 8C, and (late model) Cadillac Escalade ESV will also increase in value over the next 30-40 years.

Cheap Cars

205 GTI's
Early Golf GTI's
Clio cup's the V6 & the R26 R
Early TT's
Fiat 500 Abarth
Supra TT
Certain unmolested Subaru's
Certain Audi "RS"
M3 CSL
Most TVR's
NSX / S2000

More expensive investments.

997 Speedster
GT3 RS 4 and other GT variants
Alfa 4C
Alfa 8C
SLS / SL65 AMG Black
Certain Vipers I am sure

No point in listing a bunch of £250K+ cars, that are already collector's items.

Before you forget back (as many on here were not around then) in the late 1980's Ferrari 288 GTO's were fetching a million pounds, and Aston Vantages were getting silly money, people were paying 30-50K (when 30K was a lot of money) over book for new 911's the market collapsed in the early 90's. 288 GTO could be had for sub 200K a few years later, classic Astons were being almost given away, 911 prices dropped like a rock.

People back then thought wrongly the market only went one direction, and they were very wrong.

XJ220 which many thought was a massive investment was another car people paid over book and were stuck with, and over the decades your money would have been placed in better investments.

When you have significant rises as seen over the last few years, get ready for significant drops at some point also.

Then factor in regulation in the law, insurance factors, getting parts, fuel. Some of these older cars could end up never being on the road.

People will always pay silly money for classic Ferraris but its a limited market the Billionaire market, and there are no cheap cars to make a million on these days. It would have been nice going back to the 1960 to buy some Ferraris to sell now, but the same could be said for wine, shares, houses...etc

More like £220k with delivery miles.

Which is half what they were when new 20 years ago, consider inflation also that is over £800,000 in today money. So not only have people lost 250K on a car or about £600K with inflation, imagine if you have put that £470,000 into property it would be worth at least 4 x that now, then factor in storage costs, and keeping the thing working. Even if the Xj220 became a million pound car in the next 10 years many have taken a bath on that car.

Definitely some earlier Skyline Models..maybe the RX-7 too...i wanna say the GT-R will too, but im just not sure..i dont think so..as much as id like it to.

Fiat 500 Abarth
Golf GTI
Golf R32
Mazda RX8
Honda S2000
Nissan GTR
Dodge Viper

I forgot to mention the Spyker C8. People are definately going to do whatever it takes for one of those in a few decades.
