I currently have the Merc A class as my company car ,mine’s an A200CDI sport.
I didn’t have a choice ,it was simply the car that was available when I joined.
Having previously had a 320d I was a little underwhelmed by it initially, but I’ve warmed to it.
Good points are build quality, high quality interior,comfortable seats,good handling ,great refinement and reasonable performance.
I seem to get lots if positive comments on how it looks too.
I’d say a 1 series is a bit nicer to drive,but as suggested above they are rather cramped in the back.
If it was my own money I’d be looking at the new Mazda 3 or a Seat Leon. Focus drives well too but interior is crap and small boot, VW Golf is a good all rounder but a little ubiquitous and the Leon does the same for less. V40 looks nice,great engine in the D4 but again not overly big,and softer handling than some.
