I’ve not taken my GTI to a franchised dealer since it’s 3rd Birthday.
Same as Tony Jazz, local Indy uses VW parts sourced via TPS and updates the VW electronic service record.
Never bothered with the extended warranty as if VW is like Land Rover (previous car), the Warranty is a branded third party product, so more of an insurance contract that they will try and weasel out of.
Nice speaking to the actual mechanic that works on my car and get a better service plus it’s cheaper.
