My vw dealer recommended the following after my 30, 000 miles maintenance.
1）rear brake at 5mm, need to change pads and rotars $420 + tax + supplies;
2) passager side front outer CV boot torn open, $326 + tax + supplies;
3) drive belt cracked/worn $170 + tax + supplies;
4) coolant flush $150 ..
5) power steering fluid flush $130..;

Please help: what are immediate and must-do? Are these quotes reasonable in Maryland area? When the quote exclude tax and supplies, are the quotes only labor and I need to pay extra for parts?

I declined the services today and would like to take it to other auto repair place for an estimate. But I need to make sure they use authentic vw parts, though.

Thank you!
