About Us

Here at Mr Diagnostic Man we have been testing vehicles across the Thames Valley since the middle of the 1990’s when diagnostic testing became more main stream. We have tested most types of vehicles and in all the majority (99%+) of diagnostic testing managed to pinpoint the vehicles issues with absolute accuracy. Stephen our owner has been a qualified mechanic and servicing the Thames Valley areas for over 40 years and has a wealth of happy customers that use him time and time again.

With a penchant for exotic, classic, sports and vintage cars Stephen is well qualified in anything vehicle related. Now looking to close down the mechanical side Stephen wanted to offer our clients a quick, efficient, professional and affordable diagnostic test giving our customers peace of mind that they are only paying for work that is needed to their vehicle. Often finding that many of his customers have been overcharged for work that is not necessarily needed he wants to continue offering his unrivalled and professional mechanical knowledge to his customers.

Here at Mr Diagnostic Man it isn’t about us its about you and we will always endeavour to offer a service that you will be proud of. Making sure you know exactly what is wrong in a jargon free way is what we do best. So why not call Stephen today on 07731 965312 to book your diagnotic test today.
