Ha! And yes, this is an interference design so make sure the timing belt was changed. Valve adjust is also important. It's done with shims so best left to someone who knows what they're doing.
Hard to tell condition from those photos but if it's ratty I wouldn't pay more than 2K. Here's mine for comparison (which I'm looking to sell for 6,500.) Those are the
rare 14" x 6.5" wheels (vs the standard 6"

) Good for fuel mileage I guess? Haha, carburetor + turbos = 13mpg with city driving.
Engine pic for reference. Common sign of neglect is missing air filter hoses -- not sure why, I guess they get tired of removing/replacing with constant repairs
