1st "free" car, an AMC Gremlin, on hindsight, probably not the best first car for any 16 yr old.
had a small block V8 with manual 4 spd. that coupled with its low weight... I think I averaged 2-3 sets of tires a year.
2nd "free" car: a 87 mercury lynx (ford escort) give me by my sisters b/f (now my brother in law) this car was super fun, gas efficient, and a great car for someone in their teens. except I did nothing but race it around every where I went. I tried teaching a g/f how to drive manual in it, and she backed into a tree, trashing the rear of the car, so my brother in law took it back
