    Can you replace an ambient temperature sensor on a 2011 E350 4Matic Mercedes Benz and do you take the Napa Credit card?

    We can absolutely replace your ambient temperature sensor, but unfortunately you can only use the Napa card at Napa stores. The good news is that an ambient temp sensor is only $27.00 and the labor is $110.00

    I am looking to purchase a used car in the Cumming area and I live in Ellijay GA. If I make the decision to purchase I want the car inspected. Do you provide this service?

    Absolutely, we do a very comprehensive pre puchase inspection.

    Would you install a Vibrant Muffler with about 3ft of piping and hangers welded on to my 2000 Honda Prelude? Also can you give me an approx. cost estimate? Thanks.

    We would have to look at the vehicle and see the muffler you have before we could give you a price.

    I have a 2002 Mercury sable & my belt on my car makes a racket & I would love to few things replaced on this car !! Y'all do tune up's as well?!

    Absolutely. We do everything from oil changes to complete engine overhauls and everything in between. And you can drop off and pickup without even coming inside. Just give us a call on Monday.

    Are they certified gm techs? Independent service contractors?

    We are an independent shop that services nearly all makes and models. We can service and repair any GM model. Our 3 senior techs are lifelong mechanics with over 30 years of experience each!

    I cannot stress enough how frustrating and disappointing this experience has been. I brought my car…read morein THREE separate times for the exact same issue--a cylinder 2 misfire--and somehow, after all that time and inconvenience, the problem is STILL not fixed. Each visit meant rearranging my entire schedule, finding alternate transportation, and being without my car for days, all for absolutely no resolution. And not only that, one of the times out of the three visits I came to get my car it was filthy like they had left all the windows down or took it for a ride with a layer of pollen all thru out the car. What makes this even worse is the completely shady communication. Work was done on my vehicle without my authorization, and I was never given clear pricing upfront. I wasn't properly informed about what they were doing or how much it was going to cost until after the fact. That is completely unacceptable and honestly feels dishonest. Every time I tried to get answers, I got vague explanations and no real accountability. It felt like they were just guessing and charging me along the way. At no point did I feel like a valued customer--just someone they could keep bringing back without actually fixing the problem. I've wasted time, money, and energy, and I'm left with the same issue I started with. This place is disorganized, unprofessional, and lacks transparency. I would strongly caution anyone against coming here unless you're okay with repeat visits, surprise charges, and zero clear communication. And not only that I have spoken with the Audi dealership and another mechanic backing that what they have done is wrong and reinstating some of the things that G2 is "claiming is wrong with the car" just to come back for another visit and blow more money on the same problem for the 4th time they can't seem to fix. My friends and family will not be returning to G2 ever again after how awful and unprofessional this has been handled.

    I am one of these people that like to fix everything myself. I just did both A/C units, my washer,…read moremy microwave, and any vintage stereo equipment I can get my hands on. One of my habits when I'm tentative about a repair is to call at least 15 places to "compare notes" and learn. I get a feel for what businesses simply want to replace parts and others that know how to "fix" a part and replace a part. I ended up calling 17 BMW repair places about my wastegate on my 2013 BMW X3 and from everything I described over the phone, every place said I will need a new Turbo. I decided to also call G2 which is a little further from my house but I also remember they tightened a loose piece of my exhaust "on the fly" when I was coming back from a road trip. A mechanic named John answered the phone and I learned he owned several BMWs. He said "bring it by Brad, I'll take care of you. But I don't want to work on that car while the engine is hot so if you want to leave it overnight, that would be ideal". We left the car overnight and John made the adjustment and told us, "this adjustment should last a while. It doesn't mean you won't need a turbo down the road at some point". We picked up the car the next day and suddenly we could feel the turbo kicking in. We were so pleased with the work that we decided to bring the car back a week later to have the back brakes replaced (all BMW OEM equipment including sensor) and the transmission fluid changed. We were experiencing a little bit of car jerking when braking prior to bringing the car in and after about 25 miles, this all went away as John told us it likely would. I was very pleased with Jenna at the front desk (she happens to be John's mother) and with Gary the owner. This business has some very knowledgeable technicians, and I was most impressed because I fix things all day and this staff answered all my questions much better than the other 17 and then performed the actual work to back this up. Very pleased and the prices very fair as it relates to "European" car repair. I will be coming back to G2 in the future. - Brad W.
