Does anyone have any experience of the Merc B, compared to the A3 ? It's one of the cars on my list to try out, as a possible alternative to the A3 when I change car later this year. I'd be interested in how they compare for ride, handling, engines, build quality and dealer experience. I really need 4 doors next time, so if I stick with the A3, it would have to be a Sportback. Note this doesn't imply any dissatisfaction with the A3 (except for the S-Line suspension, which I wouldn't go for again), as the rest of the car has been excellent (as has my dealer). The 2.0T engine in particular, is an absolute cracker.
