    “Brilliant service and great string quality at a decent price. My new stringing place! Ray took his time to took to me via phone calls/whats app and treated me like a friend in a way and not just a customer. I will use Ray's services for as long as I play tennis! He also recommended a lovely new racket to me, which did indeed ease the pain that I've had in my wrist and elbow, after years of playing with stiff rackets. All the best, Ray and co!”

    High Performance Mot

    ★★★★★ 4.9 (109 Reviews) Top rated Open

    “Professional, courteous, efficient, and accommodating, I thoroughly recommend this company! Being unable to obtain an emergency slot from my Romford dealer, I urgently needed a first MOT for my very 'standard performance' VW Taigo, so was unsure if High Performance MOT would be interested in helping me. They immediately returned my missed call; which I found most refreshing, and on explaining my dilemma, and being very local, was booked in there and then! 40 minutes later, and for a very reasonable fee, I was being shown how to obtain details of my MOT on the GOV.UK website; (Pass with no advisories). I am so thankful to have found this amazing company, and so grateful for their care and consideration in dealing with me. A huge 'Thank You' to all the gentlemen in the team, you are now my 'go to' for anything car related!”

    “I have been a customer here for the last 15 years ! I was there today with a large nail in my front tyre and I thought to myself, here goes another £250 :-( Then I am greeted by a lovely lady at reception, warm, friendly, welcoming but professional and works like a busy bee - answering phones, greeting customers, look to keep everything running - she is absolutely wonderful ! The tyre chap came back saying that they can actually fix the puncture and I did not nee to spend so much - what a relief ! The chap was on the ball and it did not take them 15 minutes to fix the tyre - one happy customer left that store. I know because they are so good you do need to book in advance, but that's what happens when you get quality work ! I HIGHLY recommend Kwik Fit Cricklewood and I do all my car work, tyres, MOT etc., there . GREAT job guys - keep it up !”

    ★★★★☆ 4.7 (389 Reviews) Top rated Open

    “Perfect Touch are a very well run organisation, every individual I’ve had the pleasure to deal with has been extremely friendly and professional. I’ve been a customer of theirs for the last few years and would recommend them as the go to garage for any car in particular high performance vehicles. I first went to Perfect Touch to have a complete engine overhaul as those that know the 911/996 comes with an inherent issue of piston and boar failure, perfect touch rectified this for me yes it was costly but a lot less expensive than Porsche themselves. Since then I’ve continue to employ their services, they know my vehicle and more importantly they know me and look after me, what sets them apart from Porsche is the personal touch of treating me as valuable customer.”

    Onyx Performance - Rolling Road Tuning, Dyno Runs, Car Service Centre & Alloy Diamond Cut Refurbishment

    ★★★★☆ 4.7 (364 Reviews) Top rated Open

    “Took my 911 to Onyx to have the springs changed for a set of 20mm lowered Eibachs. Really friendly service, a nice clean unit and Ben kept me fully up to date on everything going on. Received the car back and although the job took a lot longer than they thought, they only charged me a bit more. Still a very good price compared to what independent Porsche garages wanted, and the Onyx facility looked a lot better than most of those too. Really pleased with how the car looks now, and the handing/ride hasn't been adversely affected - it really feels planted to the road now. While I was there I couldn't resist a run on the dyno, something I've not done for many years! Definitely a lot of fun, and nice to get a graph to put with the folder of my car, along with the videos of it on the rollers. If you have a performance car definitely do this if you are local. All in all, a great bunch of lads with a nice business/facility going, and I'm sure I'll be back at some point. Thanks!”
