Thanks Harri, its a good tip! so if I go for a 1-2 year old E230, I can be sure of its quality (Ofcourse, provided its properly maintained). I've bought used Chevy and Nissan brands before and they turned out to be troublesome.
Good to hear you'd a fantastic experience with Merc, but any trouble in particular I need to watch out for when going for a used model?
thx
