My dad's got an old '86 300zx he wants to sell to me for a grand. I was wondering if i should do this so i can have a back up car for when the caddy is being worked on. The problems are that it's got 300k miles on it, it's an auto trans, and it's a NA (NON-TURBO). I know my dad took great care of it and never beat the shit out of it, but still it's old with high milage. I was just wondering if I should do it.
