The '92 300E was IMO the last of the great MBZ 300E cars. New type steering wheel, all the nice wood inside the car, upgraded trans which starts out in first gear, simple yet efficient M103 engine with all the upgrades from previous years. 93 was the real start of the wiring harness problems. After this, MBZ tried to cheapen their product to compete with Lexus, which looks great on the outside but has styrofoam and cheap plastic behind all the panels. Starting in 96, MBZ set out to build a cheaper car with less build time and started down the wrong road. Only in the last two years have they finally gotten their act together. Talk with several MBZ mechanics to get further opinions.
