Price isn't bad, a fair few owners for 37500 miles. May have been driven in town a fir bit for that low miles, so check the clutch isn't slipping or juddering. If you are concerned that the miles aren't genuine, have the rear beam bushes checked. at that mileage, evn at 5 yrs old, I would expect them to be pretty good. If they are well knacked it may have done a few more miles.......??? The mk4 is not too easy to "clock" though, so you should be ok. To have theroof painted (dents will be easy enough, depends how bad they are.
Oh, worth chceking the headlight mounting clips at the front. They are known to break off easy in an accident. Repair kits are available for the top mounting lug that snaps, you should be abe to see if they have been repaired. Thsi may indicate a shunt at some point.
Otherwise, do an HPI check on it, online, good peace of mind for 40 notes, and go get her!
