    I enjoy working on my own vehicles, but with limited time, tools and at time knowledge I looked for help and found Cory and Heather. They have been nothing short of professional, friendly and very honest. I will always own a BMW of some type and will only bring it to Ultimate Bimmer Services to diagnose and repair my BMW.

    Thank you Cory and Heather !!

    Excellent place, work done on time and far less than the other BWM repair facilities in the area. Great people to deal with, very professional and courteous. Highly recommend to everyone-give them a chance to earn your business also-you won't be disappointed

    After using other independent shops over the last 11 years for my 745i, I was finally told last year to cut my losses. I then stopped in to meet Cory and Heather. Cory took on the dreaded weep hole leak that is the death of these N62 engines.. That was a year ago, and now, after many more enjoyable miles (and help with a few other fixes), I'm happy to say they've taken great care of both and my car. They are honest and fair, understand our addiction to these cars, will explain every detail of the repairs and why, and can take on any issue that the dealer can at a fraction of the cost. A great service for the BMW community. Thank you Cory and Heather

    I own two BMWs - 2001 325i & 2005 X5. Cory and his team have serviced both of them, and have done an exceptional job. Cory is honest and provides you with the necessary repairs along with an estimated timeframe (i.e., needs to be done now verses 6 months from now). I highly recommend Ultimate Bimmer Services.

    I own several BMW's 1997 M3, 1998 M3, and a 2006 X5 4.8is all of which have and will continue to be serviced by Cory at Perfection Automotive.

    I have been to other shops in the area previously and they do not compare to Perfection Automotive. They are above all, honest, and their prices beat their competitors considerably. And most importantly unnecessary repairs are not performed where I have been to other shops and was told I needed a particular repair when in fact I did not. Being a BMW enthusiast I am very particular with whom works on my car, I completely trust this repair shop with my automobiles.

    I was experiencing the reduced engine output message while driving in hot summer weather. I went to see Cory and described the conditions as to when they occurred. He thought it was the HPFP problem and with a quick read of the OBD confirmed his diagnostics. I had the problem fixed and have maintenance exclusively done by Perfection.

    They are fair, reliable, cost effective and most importantly, honest! No extra charges for services not needed, unlike the local dealership.

    Being new to owning a BMW, we wanted a place that we could trust with fair prices. We had trouble with our X5' s door. We were referred to Perfection Automotive in Nashua NH. Both Corey and Heather were extremely knowledgable about what was wrong. Both my husband and I have crazy schedules with our kids, they were extremely accommodating and helpful. Highly recommended. We will go back.

    Corey and Heather were amazingly accommodating with assisting me when I was purchasing my used X5. They met me at their shop outside of their normal operating hours to help determine any needs my car may have and recommended repairs. I did end up buying the car and brought my "New to me X5" to Corey for routine repairs, and I have been impressed with Corey's thoroughness and professionalism, I won't bring my car to anyone else!

    I called because the sign says BMW SPECIALISTS. I asked about having my 94 325is brought in to have it checked out. it's over heating. Water pump perhaps? Maybe something to do with the radiator?

    I was told to have my car towed to Dublin NH where "an expert may have a better understanding of the problem" because "this is not the area of my expertise"

    Take down the specialists sign and Save everyone the time! Least they didn't rip me off though. Thanks.

    We are BMW specialists, and only service BMWs.

    TJ spoke with my wife, who runs the office. Heather told TJ that we would be happy to diagnose and repair his vehicle. When asked if his particular model and year was our area of expertise she answered him honestly. BMWs that are 20+ years old are not our expertise but we are comfortable servicing them. Because he was looking for a specialist for his specific 94 325is she recommended a reputable shop who's expertise was older BMWs. Heather suggested having his vehicle towed to prevent any further damage. She did not intend to offend him.

    These guys are great. The work is done right the first time, their prices were better than the other local shops I checked out, and their waiting area was clean with complimentary food and beverage. I am found my new go to shop for my BMW, and it's Perfection Automotive.
