THe GT-40??? I said affordable
I guess there are a couple of ways to look at it. A car that makes a real splash- even in retrospect when introduced, like the 2002, or the trend of the past decade to apply retro styling to a new car, like the new Mustang. Yes, I think the new Mustang will be a sure winner in 30 years. As for making a real splash- the Chrysler Mini-Vans did it in 1985, and started an automotive revolution. But will any minivan ever be a classic? Not likely! Recent splashes have been the new Chrysler 300, and Magnum / Charger. These may become retrospective classics, but it's a tough call. They're not really stylistically related to anything Chrysler did before, in spite of the names from the past. Yet they aren't blatant rip-offs of their ancestors like the Mustang is.
How about that new Pontiac roadster thing? (Name escapes me at the moment, because I'm not interested enough). It really looks great, and kind of recalls the glory days, but still doesn't resemble anything made before, except maybe the original Corvette. It may well become the sleeper classic of 2006, but to qualify, it needs to prove itself as being a good overall car over time.
