I took a free oil change offer from what looks like a reputable "German autos only" independent shop. They ran a 14 point "honest" evaluation of the car.

My car supposedly needs these items fixed:
1. fan clutch bracket & belt shock - $400
2. engine mounts - $350
3. idler arm & steering shock - $200
4. engine service for rough idle and economy needle not at full left at PARK, bad mileage, possible oxygen sensor - $300-500 possibly more?
5. Front shock mounts - $250

Anyway I can check these items to see if they actually warrant these repairs? Are the quotes fair?

Thanks
