I have a 2008.5 Speed3 with 57,000 on the car and I called 4 dealers to get prices for changing the plugs. They ranged from 300.00, 223.00, 190.00, and all the way down to 91.00. I live in the Atlanta Ga. area and cannot believe the discrepancy in the the pricing of these 4 dealerships. Has any one ever encountered this with pricing on anything for our cars, please feel free to comment.
