Really helpful staff. Car had its belt done here, and when i needed advice, they were so helpful. It wasn't my belt. It was another issue. But thank you for being so helpful, so I appreciate it.

Great stock of nippon spares. Came quite in handy for last Skyline replacement. Delivery took about 6 days to get to me in Dublin. Would 100% recommend.

My son’s car had had a diagnostic elsewhere. It needed a new turbo and after speaking to Josh I felt confident that he would do a good job. He arranged recovery and called me with updates about the car. Absolutely brilliant customer service and very honest.
