1977 Mercedes 450SE Shakedown run

This is my K jetronic 1977 W116 450SE, Id bought this car and drove it 450km (280 miles) home after fitting a new starter and adjusting the propane gas system, This is the shake down test before I began to sort out the many issues this old girl had.
Id recently had a Stroke (TIA) and lost a chunk of skills based memory and some physical function and working on these old girls was my therapy.
