People here have no class... Beemer hands down mate, and i can vouch for that since hav driven E C S CL class for Benze, and from 1 series 3 series 5 series and 7 series for the Beemer...pleasure of drive , comfort, safety beemers are better, benz has taken a bit of a hitting since they took over daimler chrysler and incurred heavy losses... dont get me wrong, a Benz is still a solid car, depending on what aspect you want it for and your budget it also depends.
The beemer is amazing for speed, but the benz is prettier. Personally I'd get the infiniti, it's pretty and it's got amazing acceleration. Between the two I'd get a benz, I just like the look more. I dont really see a huge difference in comfort or features. Most of the luxury cars have nice features. I think it would depend on how old I was though. Fast cars are extremely tempting at the moment.
That is based on basically on personal opinion. Unless you want to compare specific details.
well if i had to, as in my life depended on it, id have an slr mclaren. so a merc.
In terms of reliability, a benz. beemers are crap.
which one would u rather have?
Benz... hands down.
