Looks pretty good and the price is in the ballpark. Check that it has newer cylinders with the 28 degree timing. Check how many hours are on the vacuum pump and gyros. Has the prop ever been overhauled? Does it have an autofuel STC? Check the wear on the tires/brake pads. Radios aren't that great but they look serviceable. Given a good lookover, you could have a few points to negotiate.
