108,000 miles and going very strong, upgraded the engine at 90k - ITG, HPFP, stage 2+ and TBE and it delivered 275 BHP and 315lbft on the rollers which says it all aboutthe fettle the engine is in, lots of motorway miles though, about 25k pa. This is key if it is 100k longer journeys on motorways, no issue, if 100k around town different kettle of fish.
Issues - air con pump failed, at about 60k, (common fault as already said) battery failed at 4.5 years, and had a wiring fault in the door (was fixed under warranty) otherwise has just been normal maintenance, has been serviced every 10k miles and always use long life oil, if well serviced pretty bullet proof very very well made car - If only everything in (this is my third mk V in the family and v v happy with choice and will be replaced by another VW when the time comes
