And the PU truck 2' off the ground on floor jacks is a big nothing. They use large, high quality jacks and have two guys raise each end together. They know where to put the jacks. As long as you do not get under the vehicle, (any part of your body), so what? You could do it 8 million times without a jack failing, unless the jack was failing to start with. Hydraulic jacks let you know when they need service, they don't pump up properly.
As for tire shops, the one I use in Hollywood is fantastic. Family owned, their techs are awesome and I'd trust them w any vehicle. When I first started using them, I'd watch the guys work like a hawk but now I just sit in the waiting room and read a car magazine from the table. Fantastic alignments for a more than fair price, they torque every lug nut, etc. If I brought an older 911 there, it would not even be close to the most valuable car in the shop.
