This was M.B.'s first year for lamda(oxygen sensor) fuel system controls. Also the emission output for 1980 cars were much tighter for all cars(grams @ mile instead of percentadge) so cars with bigger engines suffered. Fuel systems, exhaust & engine componets all were modified. Find a good 1979 & you will go much faster.
