When I was 15 my parents bought me a non-running 20 year old pick up truck. No AC, No power steering, No power brakes, lap belts, etc. It cost them $800, If I wanted to be able to drive it, I was told that to put in some sweat equity, I had to help my dad (who is very mechanically-inclined) to basically restore it over the course a year. We pulled it off, and I drove the F-100 until I was a senior in high school.
If I were considering a vehicle to purchase for my kid(s), I would probably lean more towards a modern sedan, something like an 2006-2012 Fusion, or similar vintage Accord/Camry. If the kid is into cars, maybe something more eclectic like a Forester XT or a Lancer Ralliart (toned down Evo), or IS300, If you don’t already have one, you might also consider getting a pickup truck, they are incredibly useful to have around, and if you get a full-sized truck, it’s have such poor fuel economy, that the kid will have to think long and hard about whether or not he/she really wants to go out on the town.
