I noticed my engine becoming increasingly loud over a few months, so I took it to my local garage (where I had my minor service and MOT done in November 2025). After a quick test drive, their mechanic claimed my timing chain was in a dangerous condition and required an immediate, incredibly expensive replacement. Since my car is a 2012 model, I wanted a second opinion before committing to such a costly repair—especially with a long holiday drive coming up.Luckily, I found Cardoc in North Harrow after reading their excellent online reviews. I emailed them and received a prompt reply from Paul, who clearly explained the diagnostic costs and next steps. I dropped my car off, and within two hours, they diagnosed the actual issue: a worn engine alternator belt, not the timing chain! The total quote was nearly a third of what the first garage wanted!When I collected the car, the noise was completely gone. To my surprise, they had also complimentary topped up my fluids and fully washed and vacuumed the car. Paul was incredibly kind, taking the time to answer all my questions in detail. This was hands-down the best experience I have ever had with a garage. I highly recommend Cardoc to anyone who dreads car maintenance—they are honest, professional, and excellent value.
