Well, you new this would generate alot of responses. I have a c43 and have to honestly say the two cars aren't really comparable the 500 great car not high in tork but killer mid range so for highway as the guys have said you really cant beet it plus with the fender flares they look super aggresive. the c43 very snappy leaps of the line mid range ok higher rpm flat which to be honest I think is detuned by the computer with a much less aggresive timing curve in the higher rpm's I honestly feel the car has great potential if somebody ever decides to make a chip. If money isn't an issue I love my C43 and wouldn't trade it for the world , but as everyone said I don't do alot of high way driving. My C43 has taken a bunch of mustangs and grand nationals. I've seen some 500e's run at the drag strip always makes me laugh all the kids bust on the big mercedes and then it just ripps them apart they just kind of shut up and stand then thats when the 30 something old guy (me ) next to them says "see told you so"
