I never really worked on my own car before but then I started observing people working on their own cars at club meets so I began working on my own brakes, changing oil, doing suspension work, etc. It seems I forgot to lubricate the caliper pins so my pads had uneven wear between the inner and outer pads. I broke a 4" long 15mm thick bolt while swapping springs which required me to trek 4 hours by bus to a dealer that had one. I thought the bolt needed 85 ft lb, not 45. Lol. Whoops.
I'm going to see if dealer maintained makes a difference with keeping my car feeling brand new about 6 years from now. My 5 never saw a garage after 96,000 km and it was kinda rough at 180,000km.
