Got a barn find!

[lowesguy]

Picked this 1991 500SL yesterday! has 34k on the clock! it hasn't been driven much,the hard top has never been off from day one, until yesterday! PO says he tried it and nothing happens so maybe hydrolics,have the day off tomorow and need to pull the fuel pressure regulator off,it was leaking from diaphragm,have a replacement on the way.
fuse c red blows,radio not functioning? its original,think the battery is new,may have somthing to do with radio? have radio code with documents.this car is a time machine! one of the cleanest I've seen,driven by a little old Japanese woman,original owner, she stopped driving years ago,she is 81 now. cosmetically superb car ,mechanically good,but need to check every hose and seals, original dealer tires from 1991,need new rubber!
