This time I've learned what to look out for and will gladly pass this half lifetime of information onto you if you too, are looking for the perfect CS. Like in all old cars check the dipstick to make sure that the oil and water haven't mixed, this may mean a blown head gasket.

While older BMW valves can be a tad clattery, a rattling top end could mean the tappet adjuster cams may be out of adjustment. Look for a noisy cam, or excessive over-run smoke. It also should be mentioned that Zenith carbs are typically a challenge to set up but usually run well once done.

The coil springs can crack too, while new shocks can make drastic improvements to ride and handling. The power steering might need a check as well, especially if vague at center. Depending on the miles the syncro may be weak on original gearboxes. When the brake discs become too thin the servos can fill with brake fluid. The diff mounting bushes are also prone to wear. Also, beware of cars that have been sitting for too long without being driven. While the mileage may be low the corrosion and need for immediate parts replacement can be costly.
