I have a set of H&R (made in Germany; one of the best springs manufacturers in the world) springs for the 124 chassis. They were used for a year or two I believe but in very good condition. These will lower the car and greatly reduce body roll and improve handling. I know these will work on the 300E (not certain if 4matic or touring use the same springs) and I believe also the 400E and 500E (not certain of those two). $125 plus actual shipping. Located in zip 70130 (New Orleans).
