Many people can’t afford to have their car down for long periods of time. German cars typically require someone who is familiar with them to work on them. If there is an Indy shop near by that can do the work in a reasonable amount of time for a reasonable cost then great.
It’s a VW tho, shouldn’t cost that much freaking money for a spark plug change. Audi, maybe. Porsche, sure but not a VW.
Depends on the Audi. A spark plug change on an A3 is the exact same as on a GTI...
