P, that dutch B50 you mention in the last post has also been on sale for 4-5 years, if not more!
Why? I have no idea, but I do not like the color (that makes the car big - which it is!), I do not like the wire wheels (which could be resold easily - more difficult would be to find the correct steel wheels), the front treatment is wrong (look at the air intakes between lights and radiator), the Nardi kit on a small engine must be a pig to set-up (and does not bring the required oomph).
Also, because it has been on the market so long, one starts thinking that the car has maybe some other faults! Or maybe, just no one is interested in a 1750 cc, 56 HP 5 seater, at that price level.
However I know similar B50, with the same small engine, that run very well indeed. You just should not expect to take any motorway climb with 3 passengers at 75 mph!
