Plenty of choice in poland, I agree, but there they are seen as a 'crap' car, so in general are not looked after, just run into the ground. Mechanics in poland will normally make do, keep a car running.
UK cars are normally better taken care of.
As I said before, be very careful buying a car in Poland unless you really know what you are looking at. A Polish MOT is very easy to buy, Poles have been buying written off cars from Germany for many many years and turning them into 'new cars'

Tarting up a 126 is easy.
