Ian Bright Motor Engineer

4.7/5

Ian Bright Motor Engineers is a friendly independent garage situated in a beautiful countryside location in Halnaker, Chichester. Established since 2013, our small team are dedicated to delivering you the highest levels of customer service. Our workshop is fully equipped and we cater for all makes and models of vehicles, offering our customers a comprehensive range of repairs, maintenance work, servicing and MOT’s. Owner Ian has over 47 years of experience, having started his 5 year City & Guilds apprenticeship back in the 70’s. City and Guilds qualifications are a lot more intense and labour intensive compared to the more modern qualifications available to mechanics nowadays, and we were taught how to fix and repair parts as opposed to simply replacing them, which is standard practice in most places today. I have experience working with older classic cars, alongside newer more modern ones too, and no job is too big or too small for us to take on! Most of my customers have been with me for years and know that by choosing my company to undertake works on their pride and joy, they will receive fantastic workmanship alongside a personalised service. We would never advise you doing anything to your vehicle which was unnecessary as some garages do purely for profit, priding ourselves on our honest core values. My son, who was trained in-house alongside me, has branched out into classic and vintage race cars and is fast gaining a fantastic reputation for his first-class trimming, and my eldest grandson Lewis is now working with me and is undergoing his apprenticeship too. Three more grandsons are also looking to come on board and keep this garage running with a strong family presence.
