    What Our Customers Say

    Phil B – Portsmouth

    I have been using JKM for all my car servicing and repairs for over ten years. Although they specialise in VAG cars, they’re also good with other makes. Very trustworthy and honest about what needs doing. Better than VW on diagnosis and repair from my experience.

    Mun Cheung – Portsmouth

    These guys 100% know what they are doing. I usually come to these guys for the big bad problems that I can’t fix myself and they always come through for me. Looked after my Corrado G60 and now Audi S4 with care and attention. Super friendly and knowledgeable. Worth the money.
