if you like the car and it is in good shape, and the engine is bad??? i may have a solution!!!!
i have used 5 cyl turbo diesel engine i would sell. it was rebuilt and has about 80k miles on it, still in the car and runs great!!
is your car a turbo model??? if not it could be converted pretty easy only a few modifications to make.
good luck with it. if you want to explore this further, feel free to email me.
