Q: Hi, Greg, and thanks for reading my letter. My question doesn't have to do with collector cars or racing, but I'm hoping you can help with the answer. What is your opinion of buying new versus used? Also, what exactly is a program or off-lease car, and do you recommend these as a good used car?I do own a collector car, by the way, a 1967 Chevelle SS 396, but I'd sure love your opinion as you write about everything. Thanks, George L., Evanston, Ill.
