Last year the M120 560SL "Samson" logged about 7500 miles including several cross country drives. The furthest being a 900 mile round trip from Wallingford CT to Buffalo NY.
This year will be a 1800+ mile round trip from Wallingford CT to Pawleys Island SC. The trip will start on the 12th of April and go to SC via 400 or so miles of the Blue Ridge Parkway, top down.
The car just got a new set of tires and a limited slip differential from Phantom Grip. New plugs were installed and everything is running as tight as a Benz.
