good offer: buy an accident car?

Hello! I got a good offer from a VW dealer for a Polo GTI (approx. 2.000€/10% below market price).The hook: He had an accident, he could show me the invoice positions: -front bumper new -coating wing v.l. new -lightlighter left new -track set -driver door painted I am now uncertain if he could not have got what on the frame. If only sheet metal/plastic is I find the whole half as wild… But track was also set. he could not tell me. He means about 4-5000€. salesman is a VW car dealership, the reperature was carried out perfectly also at VW, all gap dimensions are perfect and you can’t see anything externally. What do you think is the vehicle available for purchase? or is the damage too great for you?
