Lamborghini

Ferrari all the way. They're obviously entering a second rennaissance with the 575 Maranello and the new 420 modena. Not to mention the crazy Enzo (although I'm not sure Enzo himself would approve).

They tried building a 12 cylinder Zcar in the 70s (the daytona) and then went full-bore into producing Magnum PI cars in the 80s (the gts line). For about 20 years I wasn't sure what they were thinking, but they're starting to make some absolute works of art. Sooner or later, they're going to come out with a model as exclusive as an F50 that will be the new 1962 250 GTO.

As for Nissan, back in 1973 they'd get my vote. As for now, anyone who votes for Nissan hasn't seen what they did to the Skyline. Anyone SEEN the R35? My only hope is that it tanks so bad that they get rid of those Renault engineers and start from scratch.
