UK, Ireland / polish auctions eu - Has anyone heard of them? [3]

Hi All. Merry Christmas!

I really need your help, im planning to buy a car from polish auctions .eu. It is a UK registered car but the salesman said the previous owner of the car was polish and brought it from the UK to Poland but never returned.

I am in the UK and im very hesitant as i dont know if they are a trusted company. Has anyone heard of them?

thank you all!
