I've made a few bucks now an then on cars .. not much, and it's been a long time since I useda do that.\
Main reason I made anything at all is I kept em so long or got 'em dirt cheap to start with and their value went up.
Right now C5 vette values are kinda tankin .. I saw one for 12k no less.
I beleive in 20 years it will be similar to the 57 chebby .. they made a ton of 'em, they are great cars, in 20 years they will be mostly gone.
The Z06's will go up in value faster and farther than standard models of course.
