Its amazing all the useless crap VW used to put on their cars isn't it?
Fortunately, far more intelligent and experienced people have since found, through talking with mates and running the vehicles for a while (several months at least), that their VW's run fine or even better without all the crap VW used to bolt onto them.
My mate has an 009 dissy, half the tinware missing, an aftermarket vaneless fan housing, no thermostat and flaps, no heat exchangers, no anti roll bar, alloy wheels on a narrowed beam fitted with "smart" tyres etc etc and as a result of all the weight saving he reckons he gets 45 MPG and 0-60 in 9 secs on the local airfield (the only place flat enough to drive his slammed bug). Its deffo ok to do this because he has had the car for ages (3 months at least) and has driven it to at least 2 shows.
I reckon VW were forced to bolt all the extra stuff on by the German government who were trying to get rid of an excess of metal and components.
This had the added benefit of increasing the price of the cars so that reduced sales volumes meant the factory did not have to run extra night shifts.
