Thanks everybody for the help.
I went to see the car today and decided to leave it be. It had some work done on the right side and there was quite a filler patch on the right rear fender and at the lower side of the rear right door.
Even though I drove it, it strongly pulled to the right when braking. It did drive ok, the gear change was a bit rough, but not too bad.
The interior was a little bit of a mess, when using the power seat, the fuse blew and the car was dead. So it has somewhere dodgy wiring. The interior seemed to be original and not been dyed of any kind.
There were dents and scratches all over. Paint was faded, chipping and rubbed away, so it would need a full respray at some point.
For this price, I think I can expect a little bit more.
