You made my day by fixing my son's car so he could use it for DoE at very short notice.

They could not have been more helpful. Very knowledgeable they definitely know what they are doing. If your looking for a re map I would highly recommend you speak to them.Posted on HanaTrustindex verifies that the original source of the review is Google. I was recommended Onyx to get my diamond-cut alloys refurbished. I am located an hour away but the recommendation was important so decided to leave my car with these guys. First impressions, the team were very polite, friendly (Essan, Ben and the guys that actually did the refurb in the intense heat) The prices were competitive. And the quality of work was super. There was slight miscommunication post the sale (which happens) but I was pleased they resolved this to my satisfaction. One idea I would suggest is advising the customer 'before' the work starts that the TPF valves may need replacing so we have the option to decide whether to do it whilst the wheels are off anyway rather than post refurb to avoid scratching the newly done alloys. Otherwise happy with my overall experience.Posted on MarkTrustindex verifies that the original source of the review is Google.
