    My 15 year old car was due for an oil change and service. I always took it to the dealer for…read moreservice since new without any problems until recently. I won't go into the details but after the last visit to the dealer I won't be going back there again. Now I had to find a reliable repair shop. I used to do oil changes and the like myself but my days of rolling around on the garage floor are long gone. I had a coupon so I made an appointment at a major chain for Monday morning. That turned out to be a total waste of time, literally. I sat in the waiting room for 90 minutes while my car sat in the same space I parked it in when I got there. I finally gave up and left. Needless to say, I won't be going back there again either. So, I decided to try Bob's, the local repair shop right here in Lawrenceville. I had a couple of flat tires repaired at Bob's over the years and I don't know why I didn't just go there in the first place! Maybe because my wife suggested it and I hate it when she's always right! :( :D I stopped in to Bob's on the way home that same morning and we made an appointment for Wednesday morning. I brought my car in on time and went home to have breakfast. I got a call a little over an hour later saying my car was ready and headed back over to Bob's. The oil change was done right, all the fluids were checked and topped off, and I didn't have to wait all day. Bob's price was very fair, I didn't need a coupon, and the convenience was priceless! Bob and Wayne were friendly and professional. My car is running great! I'll be bringing my car back to Bob's again the next time I need service or repairs.

    Dishonest Auto Repair Shop - Overcharged and Poor Communication…read more I had a frustrating experience with this auto repair shop. After the service, I asked for a receipt and was told it would be emailed. A day later, I still hadn't received anything, so I sent a follow-up email--no response. I had to drive all the way back just to get my receipt. When I finally got it, the receipt was vague and unprofessional. It didn't break down the cost of parts and labor--instead, everything was lumped together. They charged me $100 to replace an engine oil drain plug cap and "diagnose" the issue. I looked up the part on the dealership's website--it costs just $12. You do the math. This kind of lack of transparency and excessive pricing is unacceptable. I wouldn't trust them again. And I just realized the receipt had actually been created that same day ( the day I drove back)---meaning they didn't even prepare it after my service like they said. That's incredibly dishonest.

    Maycol, Kerwin, and the other staff are great. I've gone to them four times on two different cars:…read morea Volvo XC60 and a VW Jetta. Excellent work, friendly service, good communication, no bs. Prices better than other places in the area. And they often get things done the same day. Like most auto shops, they have a waiting area with a few chairs to sit and work. Plugs available if you have a laptop. Can also walk to the strip mall next door in three minutes while waiting; many places there to sit, eat, and get groceries.
