I say new. I love the luxary I have with a new car. I like the fact I am not having to spend most of my time trying to preserve the vehicle... I am enjoying it. The classic are great, but I would want a 69 SS 454 with the RS hide-away lights.
I do love the new cars but I'm far too cheap to endure such a car and insurance payment. But I won't knock someone for spending the fruits of their labor on something that nice.
I guess I am the odd ball because I think this car is sexy. I love the classic cars but if I had to choose between the two I would go with the newer one.
