Keeping it well maintained is my goal, what would you recommend for oil change intervals for the gti?
There are two service schedules, one is 10k or one year and the other is 20k or 1 year (long life). Basically its an annual service.
The log life one is the default from the factory and if the previous owner had done 60k since 2014, its probably been on long life.
Things I would probably avoid in a 60k second hand car would be :
DCC (the shocks are expensive when they go and they will go in the lifetime you have it)
Sunroof (over time that will be a problem too).
The paint is supersoft and the pearlescent colours (pearl white or black) are expensive to patch up. Get one of the other colours.
19 inch wheels can or might have already buckled and the tyres are expensive too.
If its a performance pack car with the LSD, this needs a service which isn't on the service schedule. Every three years, its about £300 a go...
Oh the other thing I've observed go wrong at 4 years is sometimes the heater grid (cabin heating)... its about £1000 to fix.
