The early to mid 90s E class aka W124 definitely went down in history as one of the best quality and best designed cars ever made. Other luxury cars may be faster, more fun, or have more features… but the W124 probably is “the best” if you’re looking just at build quality and well thought out design details.

As a car nerd though, I never felt the need to buy one because they just seem fairly boring- other than a few rare models most were 4 door sedans with automatics, fairly small engines, and soft non sporty suspension.
