Broken door handle on Mercedes C220 AMG
Customer Service
Visited the garage and Stuart checked the issue. A new door car was required but as it was a specific spec the cost would be over £770 just for the door card. A mechanic suggested purchasing just the handle and bring it back in to get it fitted. Dropped the car in today and collected it later in the afternoon. The car now all sorted and I’d like to thank Richard & Stuart for sorting the car out.

Friendly staff, but overpriced
Customer Service
Sent my car here for an MOT. It failed and they quoted me almost £900 for the repairs and told me that it would be a days labour to repair. They were very friendly over the phone, and did explain clearly which work was required and why. I got quotes from three other garages for the work, none of which were more than £600. I had the work done yesterday at another garage. I dropped the car off at 8am, and had it back by 2pm, so it was definitely not a whole days labour. I probably won't be going back here again. Not sure if this overpricing was because of COVID difficulties, or because they want to get some cash in for Christmas, but either way I didn't find this to be a positive experience.

Thanks for your review Isabel. We would just like to add that a new calliper was included in the quotation we gave you and did explain that it maynot be required if we could free up the pins/ sliders. This part alone cost £106.74 inc vat which would have been deducted from you invoice if not required. I do recall you also asking for a payment plan as you could not afford the full cost in one payment. We were sorry we could not accommodate your request in these difficult times. We hope this did not reflect in anyway your review. Its a shame that you did not give us the opportunity to give you a like for like quotation as parts prices do differ considerably. We quoted on quality OE parts not cheap aftermarket products. We like to use parts that last, hoping that it saves you money in the long run. Quality is remembered long after the price is forgotten. Thank you for your feedback.
Excellent local garage you can trust
I contacted Stuart directly as the office was closed due to the Covid19 situation. I explained the issues and I was invited to pop in to get my car checked, Faults were diagnosed and parts were ordered. Date set for repairs to take place. Dropped car in 3/4 days later & as promised repairs were completed within a 4 hour window. Great customer service from both Stuart & Richard who’s generally in the office. Thanks guys

Customer Service
We’d bought a second hand car from a garage in Bristol, on driving it home it developed a few issues, we contacted the garage and explained who told us they use Williams AutoTech for the cars they sell if there’s a problem, if we take it there they can have a look and get it sorted, we did, as the car was under warranty we didn’t give it a second thought, we received a call to say there were brake system problems and they would replace the whole lot, we picked the car up and all was good, however, a couple of weeks later we took the car back to have something else checked to be told it was brakes again and the suspension, we gave them the go ahead to do the latter but queried the brakes having been told they’d been done, we were told they’d discovered it while doing the suspension work? I contacted the garage that we bought the car from to ask why we were being told about brakes again to be told Williams hadn’t done what we originally were told? After getting nowhere we decided to get a second opinion from another garage who explained the brakes were all fine and didn’t need touching, however, the suspension work that Williams AutoTech had done was faulty as they’d used cheap parts instead of genuine ones which we’d been charged for. We could’ve gone back to Williams Autotech to get it rectified but didn’t want the hassle, be accused of lying or being overcharged again. Would advise anyone to save their time and money if you plan on using this garage!

We would like to take this opportunity to clarify a few key points that the customer has quoted incorrectly. 1: Returned a couple of weeks later. This was actually Five Months Later prior to the vehicles initial visit. 2: Customer mentioned heavy brake wear dust on the front offside wheel. We carried out a brake test at a local mot station. It failed the test on a sticking caliper. The vehicle had covered 5,000 miles prior to its previous visit. We un-seized the caliper Free of charge while we carried out the suspension issues. Advised the customer if the fault returns a new caliper, disc's & pads would be required. We quoted for these parts in the event that the caliper may fail in the future. The Good news is, It must still be working fine if the other garage has given it the all clear. 3. Replaced with cheap parts & overcharged. Customer requested O.E parts & was charged the correct price for those parts fitted. These parts carry a manufacture warranty of one year minimum. 4: We would have replaced any failed parts within the warranty period free of charge including any labour cost. We were not given the opportunity. We strive to keep all are customers happy & provide a top class service. Feed back is very important to us so we can learn from any mistakes. We hope that this review does not affect any relationship we have. We wish you well in the future.
Exceeded my expectations
Customer Service
On Friday 03.05.19 driving to another garage and my car started to smell of burning so I quickly parked up and went into Williams Autotech to ask for some assistance. They came out straight away to check and diagnosed that the clutch was burning out. I was given advice and a quote. They even said they would fit my car in the next day, a Saturday but couldn't guarantee the work would be ready until the Tuesday. On the Saturday morning I received a phone call to let me know the car was ready. The mechanic had even worked on his day off. My car was repaired very quickly and efficiently. I was very pleased with the service and would recommend Williams Autotech.

A Brilliant Garage!
Customer Service
I took my van in for a recent MOT, which unfortunately brought up a few unknown problems. The guys let me know the problems and talked through in great detail. They then resolved them in a day (including about 7 hours of welding), and even managed to save me a bit of money in the end. Trustworthy, skilled, honest and a great garage.

Outstanding service

My car was with this garage for approx 4 weeks for major repairs. From the start they were so helpful and kept me informed of what was happening and price at every stage. They were transparent in their work and explained everything. The service and work was absolutely outstanding I will definitely be using again and wouldn’t hesitate to recommend. A gold star service

My review
Customer Service
By computer they found the fault causing engine light of my Merc C220 CDI 2012. Pressure sensor for DPF was renewed. The price to repair was reasonable and told me before starting the work. The car was picked up from my house and delivered to my house. They did the job on time. He arranged for me 1 year guarantee. He explained to me how to take care of DPF.

Outstanding customer service
Customer Service
I contacted Williams Autotech as my engine management light came on. They managed to fit me in same day to run the diagnostics and identify the problem to give me a price for the repairs. The quote they gave me for repairs was great and they were happy to deal with my warranty company direct to save me the hassle so I was very happy to book it straight in to get the work done. They fitted a new temp sensor, dpf sensor & ran a DPF clean which was all carried out quickly and efficiantly the same day. Their customer service is outstanding and I would not hesitate to recommend them to family & friends, one very happy customer.
