Emissions testing service near Seabrook, NH

They ruined my rims and broke a part in my car, replacing it with a generic instead of OEM part. They had their 14 year old sons working in the back, practicing on the vehicles. They denied it. Even though the kid just told me he was learning and working on the cars back there! No wonder why they damaged my rims! When I tried to confront the manager, he got in my face and started screaming at and intimidating me, a small female. When I told a lawyer who was a lifelong customer of theirs about what happened, he said they screwed him over, too. He won’t use them anymore either. Dupont heavily advertises because they damage cars and then intimidate, lie to, and blame the customer. Especially to people here on vacation, because they don’t get the repeat business that many other mechanics depend on. They are completely unethical. Avoid!

Kyle diagnosed and repaired our electrical problem, which dealership could not fix. Great, Great, Great work!!!!!!!!

I’m very lucky to find this service shop for my Mini Cooper R53. It's my first Mini and I want to rebuild/upgrade/keep it for a while; satisfied with the professionalism.

Horrible, worst service I ever witnessed! Research the BBB if you have any doubts! I was with my friend through all of this and kept telling him to stop bringing his car there. My friend never had to consult a lawyer about service and harassment in his life before, absolutely terrible service and the guy has no time to answer questions once Derek has your money to pay for his flying lessons! I noticed once anyone leaves a poor review on this midgets shop the kid goes ballistic! There webpage looks like a big shop with a lot of experienced workers, it's simply him and his wife with a garage for 2 vehicles. Derek tells everyone "Don't research anything online, published books or otherwise" and try’s to discourage anyone from this. He is always frustrated and about 2 seconds away from a heart attack, he doesn't listen and his "partner in crime Mila" is expected to patch up any issues Derek creates with any customers. I had to talk my best friend out of doing anything irrational because of the tons of money he spent for garbage workmanship by this extremely irritating little oompaloompa! These jokers never give any info. such as the VIN# from the car a used engine came from, or documentation on the mileage not simply "Oh it's got less miles than yours and looks really nice!" My friend just called him for some answers and I quote "If you want more horsepower out of your M3, buy another car!, I don't want to ever see that car again!" Once a poor performance review was left, Derek texted his private phone and said to "man up, and fix this problem with Mila" then Derek left a voicemail totally harassing him! Unbelievable for any man or child, let alone a business. He also had his M3 towed there when he had only about 120 miles on the "new engine" and the A/C belt was shredded (which means he did not install the A/C unit correctly or placed a severely used belt on it.) Think they would fix there mistake and apologize? Not a chance, He was handed a bill for the work for about. $250. I also get the feeling my friend was easily taken advantage of being a disabled U.S. Army, Infantry Veteran. Nice work Derek! I'm sure Mila can "man up" for your extremely poor and totally unprofessional performance! DO NOT BRING YOUR VEHICLE TO PRECISION BMW REPAIR in Brentwood, NH.
