My guess: car got totalled by the insurance co. (or, the guy had no insurance and/or no uninsured driver ins.), he bought it back, and is hoping for some bonus $$$.
(I bet it also has a crapload more damage than he'* letting on, since he won't let anyone drive it.)
Here are your options:
Option 1): figure in the cost of a whole new cradle, control arm(*), and associated suspension parts (plus probably steering parts), plus body work, etc., and subtract that from what you'd pay if the car were undamaged. On second thought, forget that...it'* totalled
Option 2): don't pay any more than 40% to 50% of what you'd get from parting it out. You might
get lucky and have a repairable car...but I highly, highly
doubt you can make this car safe again economically. (Furthermore, if that car has been totalled and now has some kind of salvage title, you'll never be able to sell it.) And with 130k+ miles on the clock, the engine and tranny will be hard (or impossible) to sell.
So basically, my opinion: that'* a parts car for interior and some exterior parts. And it'* already overpriced.
P.*., is there some reason you don't like your wife?
