Porsche 928 S Manual

JZM, the brand and purpose JZM’s origins begin in 1983 driven by a passion for the very special 911 sports car developed and refined over 60 years. A passion that has not wavered, we love Porsche as superfans do, after all three quarters of them are still on the road today. Our thing is – all the best bits – Porsche GT’s, RS’s, special models, rare beasts and exemplary examples are our niche. We are here to keep these beautiful things on the road, running at their supreme best. JZM Service Porsche love being looked after in the correct way with the ‘TLC’ Hans Mezger would approve of. We were around in the early days and still apply our knowledge and experience to every car we handle. For us servicing a Porsche is to look after an automotive thoroughbred. JZM Fine Tuning With such a highly refined car as a Porsche, there are few margins for improvement. We can tailor a car for your driving aspirations and over the years we’ve tried almost everything, which informs us of what works and what doesn’t. Our experience is a tuning fast-lane to your Porsche expectations and wishes come true. JZM Future There’s not a Porsche we haven’t relished engaging with, and there are a few tricky ones but, even as petrolheads the latest Taycan is testament to the Porsche DNA we understand and love. The GT’s of all eras are in our blood and we continue to cherish and nurture these fabulous driving machines. JZM Commitment We’re honest and as up front as we can be, we tell it how it is. A car is made up of thousands of moving parts and electronics, they’re complicated enough. Every Porsche at JZM is treated as a favourite – a bold statement and a big commitment, but after 40 years in we’re in too deep to get this passionate about anything else. Machtech 1983 Machtech opened the doors in 1983 as Bosch petrol injection and diagnostic specialists. Steve McHale became one of the first of very few Bosch Systems Technicians in the UK.
