bit of both to be honest... you'll have to pay "RS tax" for almost all parts, some of them are frankly eye watering, like the £650 air filter cover.
a lot of work seems to need the engine out too... plus gearboxes are around £4k to fix...
suspension is another couple of grand to sort when it breaks, and talking of brakes, they are over a grand for the Audi stuff...
but apart from all that, they are ok....
