$4k is still sounds a bit high to me but then my first car was a 81 dodge mirida with a /6 auto that I paid $600 for. I drove it for almost a year without any problems till I slammed into a toyota truck at 30mph

. It still ran and drove just fine but it was kinda hard to see at night without headlights

so I sold it. How bout something along the lines of a Ford crown vics, dodge diplomat, chevy monte carlo, caprice, ect. All those type of cars are generally fairly big, reliable, safe, available with a v8

, have cheap parts, and since they are all RWD it will give your parents a good reason not to let you drive in the snow.
