I searched locally for pads and rotors without finding what I wanted for my 2002 BMW 530i. I called and placed my order and got exactly what I wanted, Brembo Rotors and Jurid pads cheaper than anywhere else and got them shipped next day air. From order to installation in 20 hours! You've got a new customer for life!! - Maddog82

My experience with partsgeek was extremely pleasant. I ordered my part and two days later it arrived and was the correct part, also about 30 bucks cheaper than anywhere else. Thank you! - stupidqtip
