For many years my dream car was an R32 GT-R. I've been lucky enough to ride in a few and drive a few of them, and i'd still really love one - but they are just WAY too expensive now that the USA can import them (gone from $20k NZD to $50k-$100k+ NZD) so that dream is likely to only be a dream now.
My second dream car, and still current, is the Mercedes-Benz SL55 AMG. Fell in love with it while watching the roof fold itself away at a car show in 2006 or so. Last (?) year i came
extremely close to buying the exact one below (i was in contact with the owner, and getting insurance/finance quotes) but i figured that it would not only take all of my savings to buy, but also i'd have to take out a small loan. And given this car is notoriously expensive to fix things like the magnetic ride suspension, automatic folding roof and other electrical gremlins, i opted to can the idea and spend that money on the house instead.
Plus, i actually want the car in the bright red colour it comes in.
As for my ultimate dream car, it has only ever been the Ferrari F50. Don't care what colour. I fell in love with it when Dad first showed me pics of it in 1995, and since then not a single other car on the planet has come close to topping it as my ultimate dream car.
Extremely annoyed though that their prices are increasing a stupid amount, so it too is looking highly unlikely i'll ever get it.
So basically, they'll remain dream cars. Luckily games like Gran Turismo feature them (hoping PD bring back the SL55 too) so i can still get some enjoyment from their existence.
