I have done a few oil and filter changes myself, but over the last decade have relied on a great local father and son garage who I totally trust. They mark a date on every filter and part they fit, and show me the worn brake discs/clutch/bit they've removed.
We even take Mrs H's brand new Audi to them rather than the dealer because we intend to keep the car for 10+ years so will definitely save more than the loss in resale value for the D in FDSH
Convenient to combine a service with an MOT on my older Mini.
