It sounds like you are looking for something older than I am going to suggest but......a '92 and up Crown Victoria is a nice ride. I used to have a '93. I loved it. I have never in 35 years of driving had a car that gave me so much for so little. They are super reliable with decent mpg and very satisfying to drive. Arguably the best years are 2003-2004. Those years have good hp (245?) and they are the last year before drive-by-wire throttle. They have that old V8 feel, but with modern brakes and handling. They are cheap to repair, too. The only thing I ever had to do with my ultra high mileage '93 was change the oil, filters, plugs, and wires. Oh and electric window motors. It just felt good to drive.
Put a 3.55, 3.73, or 4.10 gear in it and aftermarket dual exhaust, and watch him have fun.

edit: Sorry, I just realized this was in the classifieds and I think you were looking for an actual car rather than advice.
