Very Satisfied
Reviewer: Pro From Dover
3/5/09 12:54 PMI found the PartGeek web site and order platform to be very easy to navigate. After an extensive search I found their price for Nivomat shocks to be significantly better that any other vendor out there. I received my order in 2 days. I was very impressed. Based on this experience I defiantly would order from PartsGeek again. I'll also recommend them to my friends.
