1998 E430's have the new engine design, and the crankshaft balancers are bad. They were redesigned in mid-year 2000. The engine in E420's does not have this problem.

The performance of the E430 is a little better - about a half-second quicker 0-60 mph, but we're still talking about a 6 second range 0-60, which is pretty darn fast.

I think '97 E420's and '98-'99 E430's are pretty darn similar - externally and internally they look exactly the same.

The big change is in model year 2000, where there were a number of changes: the instrument cluster and steering wheel were redesigned, front / side curtain airbags and rear door airbags become standard, the front and rear bumpers were redesigned (along with a new front air dam), the hood and grill were also subtely redesigned (which nobody seems to realize). An On-Star-like system became available, which requires a subscription.
