Uuummmmm, possible a fault thermostat? Best thing to do would be to get it scanned using VAGCOM, but I guess if you are buying from a garage you won't have that opportunity.
Bushes sound right for the rear, probably £150ish for a garage to do so factor that into your deal I guess. Steering wheel not straight is 'just' tracking.
One of the other guys will be along to confirm or deny my thoughts.
Welcome BTW
