The R129 was a real tour de force for 1989! Alle electrical gadgets were a huge luxury for that time, the demand for the R129 was high. Even so big that Mercedes could not keep up production and the waiting times were easily one year! The few lucky ones that were able to get a car in a reasonable time could easily sell the car with a profit of 5000 Deutsche mark!
