Based on an article in the April Car & Driver mag. the E series is coming back with an E500 series. Not sure how accurate it is - they state that the 1995 model had the four ovoid headlights - WRONG - I have one parked in my garage that proves them wrong.
Anyway, the article states that the E500 will be 302 hp V8. In addition, it says a 463 hp supercharged model will be available later on (AMG version). Don't believe how much they say just because they do not even seem to have a clue when the front headlights were changed. Says the two diesel powered models will NOT be available in the US.
In another article in the same month C&D they test the 2003 SL500 and believe it or not complain about the climate control complexity - imagine that.
I sure wish they would come out with a brand new 1985 300D

with the climate controls from a 1983 240D. I believe I would head on down to put my order in.
Just my preference I guess.
