Read the old posts on the site about registration. if it is a
2000 it is very very tough, also 90s cars are very thin metal, came from Belarus as opposed to polish steel. they rot very very fast. (floors,inner wings even seen roofs)
If you speak Polish then I really can't see a problem finding a decent car, many many polish 126 sites with some very good cheap cars about. If not, Allegro is always good.
I am sure you know a Polish MOT means nothing at all, just a bit of paper. the car will have Polish insurance so you will be covered to drive it back here, trying to change registration at local 'UrzÄ…d Miasta' can be a pain if you are not 'zameldowanie'. somewhere in PL.
Tryng to cross the border on a UK passport in a Polish car was not a problem though, just make sure the car is not nicked, they will check on the border
