Jon has always been involved in the performance side, and when he moved with the Company to its previous site he became Service Manager. Jon used this time to gain a real in-depth knowledge of tuning and modifying Vauxhalls, as demonstrated by his Nova, which used a 2.0 litre 16 valve Vauxhall engine, installed and turbocharged by Courtenay, and with their software controlling the engine management system. Since then, Jon’s cars have included a Calibra 3.0 V6, a throttle bodied 2.0 16v Nova Sport, an Astra G XEV turbo, an SRi Astra Turbo (one of the limited edition of 500), a Vectra ST200, and more recently a VX220 2.2 16v, 2 Astra VXR’s, a Lightening Yellow VX220 2.2 and 2 Corsa VXR’s.

As a result of Chris choosing early retirement, Jon took the opportunity to buy the business with his partner, Sarah, and they have continued the business it in its winning ways, more recently being involved with projects for Vaxuhall Special Vehicle Operations, Lotus Cars with the development of the VX220 Turbo Sprint car, 888 Race Engineering producing performance products for several of the VXR range of cars and also in racing in the Dunlop Sport Maxx Production Cup with an Astra VXR. Racing for us began in 2009 when we were asked by Adrian Churchill to improve on his competitive but very poorly mapped Astra and we were glad to help out. This partnership developed into full race support and saw us win the 2010 Championship. Following on from this success we ran the same car 2011 in the renamed championship, the Production Touring Car Trophy, and again won the championship. 2012 saw us compete in the championship and 2013 we are concentrating on Time Attack, as well as enjoying track days around the country for fun.

The Courtenay workforce consists of two experienced mechanics, David ‘Percy’ Postle who has been with the Company since its infancy, and Mark Ratcliffe who has a wide knowledge of Vauxhall products from his days at a local dealership. Mark Ashford and Mark Watts both have extensive knowledge of Vauxhalls, having owned and driven countless Vauxhalls and are the voices on the end of the phone to deal with sales and general enquiries, along with Jon.  The end result is the knowledge and capability to transplant engines, gearboxes and running gear from one Vauxhall to another, and developing our own Turbo installations and brake and suspension upgrades means that Courtenay know Vauxhall’s literally inside out. With the kind of knowledge and skill that go into producing such enthusiasts’ dreams, our Courtenay team can service standard cars with ease, from changing the engine oil to changing the engine itself, from routine servicing on a Corsa to building a 500+bhp turbocharged Astra, Corsa or VX220, Courtenay remains THE place for Vauxhalls, standard or modified.
