Full service with MOT on my Fiesta st2

I am very pleased with the way my car is performing after its comprehensive service yesterday. The car was clean when I took it in and even cleaner on collection.The car was ready for collection early afternoon and I was picked up promptly and taken to the garage. I found all the staff I interacted with most helpful . The car passed its MOT and no advisorys were necessary. I thought the cost for all the work done was on the high side but then with the cost of living as it is I understand why. I have been using Days for some 25 years and I’m more than satisfied with their standards. I’ll be returning next year.

This Independent Garage is without a doubt one of the finest in the UK and is as capable as any main Dealer without Main Dealer costs. I have been a Customer for the last 15 years and on each occasion I have received top quality service and the knowledge and expertise is second to none. Starting with James the Owner at the top and his Staff who are courteous and personable. Over the period I have been using this Garage I have seen it grow and it deserves the Awards it has won. Thay also serve a nice cup of Coffee which is also consistantly good. I left their Garage last Friday after major repairs and it felt like new again. Thank You.

Our car went in driveable for a full service, cambelt, and inspection. It came back with severe running faults that had not existed beforehand. J Day failed to diagnose the fault, insisted their work was fine, and blamed the age of the engine. We had to recover the car and take it to an independent specialist, who found the fault and concluded it was highly probable it had been caused during J Day’s cambelt work. At that point, whether this was extraordinary incompetence or something worse almost becomes irrelevant. We had paid professionals to diagnose and repair a car, yet had to fund recovery and an independent inspection, spend months arguing, and send a letter before action to get a resolution. The most disturbing part is what would have happened if we had trusted them. We could easily have spent thousands repairing or replacing an engine that wasn’t responsible for the fault. A garage that gets something wrong is one thing. A garage that gets it wrong, cannot diagnose what it has done, and then digs its heels in when independent evidence proves its diagnosis wrong is something else entirely. I’ve never dealt with a garage so determined, in my opinion, to defend the indefensible. I wouldn’t let them near another car of mine.

The trader replied (on 22/09/2026)
We are disappointed to read this review and respectfully disagree with a number of the statements presented as established fact. This matter concerned a technical dispute involving a 25-year-old vehicle. We thoroughly reviewed our contemporaneous workshop records, the customer's submissions and the independent specialist's report. Whilst the specialist adjusted a crankshaft position sensor and expressed the opinion that it was "highly probable" it had been disturbed during the cambelt replacement, we did not agree that the available evidence established responsibility for the wider allegations subsequently made. The report itself also recorded pre-existing engine wear and below-factory compression. Despite disputing liability, J Day Engineering chose to reimburse the customer in full as a commercial decision because the management time required to continue the dispute was disproportionate to the value of the claim. This was expressly agreed by both parties as a full and final settlement, without any admission of liability and without any court determining the issues. We fully respect every customer's right to leave an honest review. However, we do not believe this review fairly reflects either the technical evidence or the basis upon which the matter was resolved. For over 26 years we have remained committed to resolving concerns professionally and fairly.

Took my BMW 1 Series in for MOT and standard service. Total time taken was 3 hours, including refitting of a tyre which had a leak on the rim. I was offered a courtesy car but decided to wait in reception and was offered cups of excellent coffee. They washed the outside and vacuumed the inside. I would highly recommend this company.

Everything was perfect for my 3 Year full service on my Alfa Romeo Tonale Petrol Mild Hybrid. Friendly welcome, service completed to Alfa Romeo specification. Booking process and estimate were excellent. Actually came in below estimate, a first for me, and 50% cheaper than my last main dealer service! The garage is immaculate, with plenty of parking. All the work completed on time. This is a total 5* experience with the car washed and hoovered for collection. Highly recommended.

Brilliant garage just off the A30 near Henstridge between Shaftesbury and Sherborne. Super friendly like your local garage but also proper big and knowledgeable and efficient like a big city garage. They do RAC warranty work on my Jaguar I-Pace as well as full servicing which is so much better value than going to a Jaguar dealer! They have also serviced my Nissan leaf recently and valeted it free of charge which was lovely surprise? Thank you !

After the car broke down the RAC contacted this garage on our behalf and happily they agreed to take a look that same afternoon. Whilst we were on our way to the garage they were already securing parts needed for the repair. Due to their swift action we were back on the road within 90 minutes. What could have resulted in a very stressful start to our few days break, thanks to this team & their superb response, we were back on the road and able to continue. We would just like to say how grateful we are for their professionalism & friendly staff. We would happily recommend them.

The came in for MOT plus major service. This was done promptly and efficiently and I was kept up to date with the progress. On collecting the car I didn’t recognise it first as it had been cleaned so well that it took my breath away. The car was found to have 2 advisories and the cost of these were sent on a separate quote. Every time I leave my cars here I feel the customer service cannot get better, but it does, 10 gold stars

J.Days replaced the front disc and pad replaced on my Audi A3 that I was advisory on the cars MoT in February. They provided me with an estimate for the work that was necessary and carried it out for the price they had quoted. I have use them for the past 9 years to service my current Audi and and a SAAB 93 I previously owned and trusted the advice they have given me. I have found their estimates to be always reliable and the cost of the final bill, so no surprises or hidden extras. I would highly recommends the service they provide and have every confident in the advice they have given over the years. I consider their charges are competitive and they provide value for money when the quality of their servicing is taken into account. I have also uses their tyre replacement and balancing service which was excellent. As I live in a village close to their workshop and they are happy to collect and return my car without charge, which I find convenient.

As always efficient. Could not believe it booked in for Thursday for a full service. And at 11 o clock I received a call to let me know that my car was ready to collect. What I also liked they did an advisories check and pointed out these issues that will need doing. I've spoken to my wife about this company and she has said she wants to take her car there. Thank you so much to this team. They make you feel so good. If the job they are doing does not take long and you can wait while they do it. Offer you a hot drink. Would recommend this company to anyone who wants help.

Work undertaken: MoT, oil change service and health check on my Audi A3. The MoT highlighted three advisories, and I was provided with advice on the urgency and cost of rectifying each repairs. I found particularly useful as it now enables more easily plan and finance my car’s maintenance over the coming year before the car's next MoT. J.Day continues to provide me with excellent customer service and advice at what I consider to be a competitive price. I therefore have no reason to go elsewhere and will continue to use them to maintain my car and am always happy to recommend them.
