I cannot begin to express how satisfied I am with the quick and efficient service Amir, Andrew and staff provided for me. I own a 2006 BMW M3 ZCP with 70,056 miles. I began to hear some rattling coming from the valves a while ago, so I decided to look into the one known issue with the E46...the VANOS. After doing some research, I decided to take it to Avus as they have an excellent reputation and also do VANOS upgrades what seems like every week. Well... Is this really the same car I dropped off a few days ago? WOW. First, Amir and Andrew are very knowledgeable and provided me all the information I needed to make an informed decision on my repairs. No muss, no fuss. The repairs were done quickly and correctly. I can honestly say that this was money well spent. While they serviced my car they were also able to fix another issue that I had and kept me in the loop as far as time and cost. I was so satisfied with their customer service and professionalism that not only did I get my VANOS upgraded, I also had them install a Dinan exhaust, Dinan Stage 2 software, Dinan short throw shifter and even perform my Inspection II (it was overdue). I will definitely be bringing my M3 back to Avus for services and Dinan upgrades. They are trustworthy, honest and have some amazing technicians that know what they are doing. You get what you pay for...and I got my car running better than ever. Thanks again, Avus!
