I think a 400E or E420 would be a nice car for you. Sure, you'd lose the coupe style, but you'd gain the power of an M119 V-8 engine, and admission into the world of "MB Hot Rods". Plus, you're already familiar with the W124 body style.

Oh yeah, how about a Volvo station wagon for a $2500 grocery getter that doesn't matter if it gets hit/totalled (in addition to another MB)? Hope your accidents are at an end with this one.
