> I drive a 2CV and B-Class, the merc has never put a smile on my face whilst driving.
Don't know about a B-Class. Try an RS6 for that particular smile on face and frown on arse cheeks combination. Mind, the smile will only last about 500 km on a full tank, not to mention the hourly labour rates on it being more expensive than my lawyer.
Congratulations on getting your hands on a 2CV though! I've been looking for one for years but nobody wants to let go of them. :-(
