I asked the tow truck driver who he recommended in the area and he recommended Rees. Not only did John fix the issue that landed my car at his shop - but the recent expensive fixes that the dealership recommended I do - he confirmed I didn't need some of them and fixed the ones I needed for ALOT less! I live in Brookhaven but I will drive to Cumming when my car needs service. Truly honest mechanic who does great work -- and efficient and responsive. You can thank me later

My experience with Richard's Automotive is far different than most of the recent reviews. I was…read morehoping Richard's Automotive could fix a coolant leak in a Ford F150 Turbo, a 13-hour billable repair and about $2,300.00. After 10 days (eight working days) and multiple excuses/lies I got my truck back with the front tires rubbing when turning, turbo leaks, and a check engine light with a turbo error displayed within 20 miles of pick-up, all documented by Ford. I gave Richard's Automotive the opportunity to be a responsible business and make good on their bad repair, they chose to defend the undefendable. Luckily, Ford was able to correct their incomplete or poor repair, provided video and written evidence that Richard's Automotive did not complete the repair correctly. Unfortunately, the Ford repair of Richard's Automotive negligence cost me an additional $1,400.00. I warn potential customers of this: if your repair is taking too long and the excuses pile up, you should be concerned with the quality of their work. Don't drive off without first test driving the vehicle.

Hickory Flat was the closest shop, so we took a chance and drove in without an appointment, hoping for the best.

Caveat emptor! What you're "quoted" at RNJ Automotive and what you are ultimately charged may be…read moretwo *very* different amounts. Never had as many problems just trying to get a reasonably accurate estimate from any auto repair shop as this one. The process with four other shops I checked out for the same repairs using same description went smoothly, so not sure why it was so difficult for RNJ. Needed a simple headlight replacement, installation of a new combo meter (circuit board that displays speedometer and odometer), and a quote for an engine swap on a Prius. The woman who provided a two hour quote for the combo meter, Nancy J., didn't know what one was - which is understandable - but apparently couldn't be bothered to look it up. On July 15 promised to get me a quote on the engine swap the next day, then almost two weeks later (July 27) said still didn't have it. Rather than being somewhat apologetic for not following up as promised, her reply was seething with sarcasm. Things rarely turn out well, in my experience, when a company is this careless and puts someone who doesn't understand the fundamentals of customer service as your first point of contact. It's not uncommon for these companies to exercise poor judgment in other aspects of the business as well. Bottom line: Service leaves much to be desired and prices not very competitive. Too many shops out there who are eager to earn your business and extremely capable to put up with this level of carelessness and sarcasm. Is this shop better than a dealership as mentioned in several of the positive reviews? Sure. But that's setting the bar really low. [Note: Nancy edited her sarcastic comments out of the allegedly entire conversation in her response. Can't help but think if they're incapable of honesty in a review, how much can you trust them with your auto repairs?]

I run a very busy company and recently…read moreallowed Automotive Dynamics in Woodstock GA to work on my truck because I am simply too busy to work on my own vehicles any more. The sensor in my fuel tank that runs my fuel level gauge was malfunctioning and needed to be replaced. I made an appointment which required me to wait two weeks into the future. I took my truck in on a Monday and it was promised back by Wednesday. Wednesday afternoon, the owner Matt Braden called me and said he had not worked on my truck because "other work had come in". This was the first insult... why did I make an appointment only to be pushed aside for other work? Matt said he had to remove the fuel tank from my truck to change the pump/sensor assembly. He went on about how hard it was going to be because it was half full of fuel. We calculated the weight of the fuel while on the phone and it was only about 150lbs. With a lift and a transmission jack, this is nothing and very simple to do. There are only 4 bolts and a few hose clamps holding the fuel tank up into the truck. I told him I could wait one more day and he said he would work on it. When I went to pick up the truck, the bill was $755!!! I was SHOCKED. He charged me 4 hours of labor to change the pump/sensor and 1 hour to adjust my parking brake. The parking brake adjustment takes less time than it takes to put air in a tire. I had no idea he was going to charge me more than a few dollars for this. I went to drive off, very upset, and then put the parking brake on to test it. I was able to drive right off with the brake on! It was delivered to me in a completely UNSAFE condition! We had to diagnose this and repair it at my shop. The problem was easy to find. An axle seal had failed and allowed oil to pour into the brakes. The brakes were ruined with no pad material left and simply slipping providing no safety. This should have been alerted to me as it was easy to see without taking anything apart on the truck... the backing plate of the parking brake had oil all over it! This terrible sloppy careless mechanic isn't qualified to even touch a brake system. (see photos) I was driving the truck from GA to TN the same day. While fueling the truck I decided I should inspect the work to make sure my truck was safe. I noticed no one had removed the filler neck to the fuel tank, as all of the clamps had never been touched and had 15 years of dirt and grit on them. How did he remove the fuel tank? I checked the other end of the filler hoses at the tank... same thing... no one touched them. How did he remove the tank? Then I checked the four bolts that hold the tank in. No one had touched them!!! It was 100% clear that no one removed my fuel tank. They LIED IN MY FACE. This truck is a farm truck with a big hole in the bed for a gooseneck hitch. I looked in the hole and you could clearly and easily see the pump. (See photo) It is held in by just 6 small screws. One hose clamp on the fuel line, and one quick couple electrical connector. This pump can be removed and reinstalled in less than 10 minutes!!! How do I know that? There is a Safety Warning Tag on my new pump. The careless sloppy mechanic pinched the tag between the gas tank and the pump leaving an open airgap into my fuel tank and leaving my truck in a DANGEROUS condition!!! I hoped the tag would simply slide out as it was made of plastic, but it had been cut by the pump when it was tightened down. (See photo) In the end, I had to remove the carelessly installed pump myself, find the chopped off piece of tag, remove it from the sealing surface, and reinstall the pump myself. (See photo) Every single thing this terrible shop did had to be undone, and redone correctly by real professional mechanics, at a loss to me. Even worse, this terrible unscrupulous thief charged me 4 hours of labor for the 6 minutes of work it took to change the pump!!! I know because I had to repeat the job. To add insult to injury, they charged me $29 for "Supplies" when NONE where used, no even one penny's worth of chemicals or material were used to DEFECTIVELY assemble my truck and leave it in an UNSAFE and DAMAGED condition! I called the owner Matt the next day, and he admitted he had not removed the fuel tank, as he knew I had caught him red-handed STEALING FROM ME. He said he would refund 100% of my money the same day. I waited for almost 3 weeks, and have never received any refund, so I have file a dispute with American Express to get my money back. I have since had to have the parking brakes completely overhauled in order to make my truck safe. This matter will appear in a lengthy Youtube Video on my Channel, and will be reported to the Better Business Bureau, and other social media outlets in an effort to ensure no other motorists are victims of this horrible operation.
