What Our customers say
EXCELLENT Based on 29 reviews Mohammed Faisal2025-09-16Trustindex verifies that the original source of the review is Google. 2014 Range Rover sport engine went bang on the motorway 7 weeks ago. Not knowing what to do or who to trust I came across Aiden at JLR Windsor online. He quoted a rough price over the phone. I recovered the car to him. He reconditioned the engine in 6 days. They provided 6 months warranty. Very smooth process the engine genuinely sounds so much better than when I bought the car 3 years ago. I’ve been driving 5 weeks no issues at all. Just been back for the 1000 mile service which he also included in the initial price. Top top guys. And if you have any doubt all you need to do is visit their workshop and when you see the amount of range rovers and jaguars parked up you’ll know how good these guys are. Simon Young2025-07-23Trustindex verifies that the original source of the review is Google. My low mileage Discovery Sport suffered the dreaded timing chain snapping that is well documented on JLR Ingenium 2.0 litre diesel engines. I contacted Aden after seeing a recommendation on a Land Rover forum, and was immediately given a fixed quote. He even offered to help organise a transport company to get my car to their workshop. I was sent updates throughout the rebuild process, with photos of the damage caused, and then later on, of the newly rebuilt engine before it was reconnected. The whole thing took 11 working days from the time my car reached them to it being ready for pick up. The engine sounds smooth as anything. Absolutely amazing, and excellent value when you compare to the costs that JLR dealers happily quote. I really recommend these guys, couldn't be happier. baljinder rai2025-06-14Trustindex verifies that the original source of the review is Google. I got my peugeot engine done.
