I ve been looking at getting an e420 on erealson is because i ve heard such good reviews from the audience here on mercedesshop. The only problem is when i go to some mechanic shop , i get alot of negative opinons about the V8 vs the e320 v6, i hear the the v6 2.6 e320 is a less troblesome engine and its more durable, too. Im confused a bit about the integrity of some of the motors thats mercedes use in their cars. One person even wnt as far as to tell me that some engine were produced at the GM plant and should stay away from those engines. He recomemended highly a straight v6 engine made in germany. How do i tell the difference.Do u guys have pic of what a straight 6 looks like versus a regular 6?

Thanks
