1963 mercedes-benz 220s Convertible White

Owned since 1992 it is time for a new care taker. This car was imported from Germany in 1983 to Florida before she purchased it. Has not been tagged or registered for about a year now but has been started regularly. She fires up and runs smoothly, no smoke or loud noises. I drove it down the road, changes gears and stops fine. I could not figure out how to operate the wipers but everything else seem to work: radio horn lights etc. Two years ago the heating core was clogged and there is a note in the engine are that the hose is not functional? There is a black soft top under the hard top, it was replaced 3 years ago and she said it still looks new. I could not take the hard top off myself but if someone really needs a picture I can get someone to help remove it. Included are various filters and parts in the trunk for the next owner. Odometer is in kilometers, not miles
