Okay, so it's a 3.2 VR6(don't let the V6 badge fool you)... pretty much indestructible and dead reliable as long as it's been maintained. I firmly stand beside any VR motor VW has produced- they're great.
These did not have chain guide issues like the 2.8 VR6 counterparts, so really the only thing to worry about on these motors is water pump and any coolant/thermostat housing warpage. MAF can be a wear item on any VW motor, but aside from that, have no worries. Give the engine a look over for any oil leaks or coolant leaks and you'll be good.
