vw item is much better quality and therefore last alot longer ... same goes for oil filters only buy vw
GSF's are OEM spec MANN filters - perfectly adequate.
Hmmm belts are probably the sorta things you wanna be able to rely on, VW I would say for them
Also wrong. GSF's are OEM spec, again, perfectly adequate.
Would I buy a thermostat from GSF - why not, I'm already running a GSF waterpump (and have been for 2 years).
