I've always, always wanted an NSX:
1991 Acura NSX
Stock they are just so oddly pleasing in a geometric sort of way
You can see so many rectangles, curved blade-like shapes, squares, feminine curves with those big door-vents, the hidden handles, there is so much going on yet it all fits together to make such a legendary car. I think the NSX, especially 1st gen, is going to seriously hold its value and I would love to buy one after my next business venture pays off!
Most 1st gens I have seen for sale have been absolutely rat-bagged.
