You oughta make list of specifics regarding throwing the car on lift to look for rust, worn out and ragged rubber suspension boots, excessive play in kingpin suspension, suspension sub-frame bushings, etc..... Hell, the list of mainenance items on the 220S (Ponton or Heckflosse) is extremely predictable. Meanwhile a wet/dry compression test and/or smoking with oil consumption will tell the story of the valve seals and if the tranny flares between shifts this can best be found after an extended high speed drive.

As first time poster on this forum, the only other thing is you gotta pay your membership dues to whoever on the forum does the inspection...... say, provide 1/2 gallon of single-malt Scotch whiskey for intelligent survey of the 220S cabriolet in LA. Am certain that somebody here will be happy to test drive the 220S cabriolet for you.
