Since you're limited by choice might you widen your search to include a 2.3?
There's one for sale on this forum.
Or there is this 2.5 which is also on the 190 forum.
1989 MERCEDES 190E 2.5-16 Cosworth in our family 19 yrs on eBay (end time 19-Jul-10 20:44:44 BST)
My 190 2.5-16 Cosworth for sale
Thanks Will, id seen that one and I emailed him but he wont take any real offers on the car and really I think its a little heavy for a car with that mileage and needing a new display. Also its too far to pop around to have a look!
jaymanek , would you like to try my manual 2.5-16V ? , I am in North London . My car is not perfect but is mechanically excellent and is well known as a very good and still tight example. I often use it as a trackday tool .
Thanks, may well take you up on this, maybe you could PM me your details as im down your way on Sunday.
Thanks
