Purchase advice: Golf 4 TDI and Alternatives

Good day, I come from near Frankfurt and came across the following car: Golf 4 TDI What do you think of the price, I expect that the timing belt has been changed but worn off tires are included.On the 5 picture you can see a crack in the seat next to the sidewalls. Besides, I wonder what is to be seen on the left above the floor mat, something worn. . Nevertheless 5 doorrs, seat heating and sports seats, my budget up to 500€(for repairs is still about 500-700€ left), exactly that, w I have been looking for weeks/months. I find many Golf 5 models, but from almost always 190.000KM, no sports seats, almost always only 2 doors and no seat heating from 500€ Nuremberg is already a long distance, 250KM, so I ask you professionals before I go there. I am grateful for any opinion.
