Being as old as it is, check the suspension components as well.
Does this car have the SLS suspension in back? If so, that needs to operate properly, otherwise it can be a substantial amount of investment to correct.

Yes, the Self Leveling System.
The rear suspension is hydraulically operated, by this time it may malfunction.
There is an engine driven pump, if there is enough weight in the back, that will trip a switch telling the system to pump more fluid back to level it out.

Ask if and at what miles was the timing chain replaced.
Look for rust in the trunk under the rear window. Also look for delamination of the glass.
Ask when the transmission and brake fluids were changed, and what kind/type of fluid was used.

1989 300 SE
Don't know if someone told you this but, real important the check the coolant overflow tank for any HINT of black staining inside. This would indicate traces of oil in the coolant, which means a head gasket failing. The 87-89 300se has a problem with this because the tolerances of the gasket were just too close, and they pretty much all leaked eventually. That's why you don't see alot of the Inline-6 gas engines from that time around anymore- head gasket failure. If you do buy a I6 from 85-92 ask about it.
Head gasket jobs run from 2500 to 5000, depending on where you go to do it.
