I can't comment on the new 'A' class, but we do own a first generation 54 plate.
The build quality of the Merc compared to that of the baby Audi is like comparing a piece of glass to a fine diamond. The driving experience of our 1.4 petrol is fairly lacklustre and the interior and exterior quality is equally not as good as that of the Audi.
It really depends on what you are looking at in a car first and foremost. The 'A' class offers good boot space, good flexibility and is a sound workhorse. The driving position is fairly well laid out and all round visibility is reasonable too.
If you want to own something a little special and something that is a cult classic which was designed with ingenuity, passion and built with quality materials - the A2 wins hands down.
If you are looking for a practical small, but largish car
confused:
), then the boot space of the early model is very generous indeed, the car is practical and could tempt you. The new model is bound to be light years ahead of the first generation cars too.
As a second car, the 'A' class is fine and we purchased for practicality as much as anything else, (eh Chris?!). As a main drive I would personally opt for the A2 everytime and if she could, my wife would swap with me tomorrow.
