Partnership proponent There are lots of reasons why people buy cars, from a change in circumstances, such as becoming a parent, to retiring. But when it comes to why people keep their cars and stick with the same brand year after year, there’s one factor that has the biggest influence: reliability. But don’t go thinking that Jaguar has abandoned what it has always been famous for – namely, creating high-powered, luxurious, rear-wheel-drive saloons. First seen in camouflaged guise going up the hill at this year's Goodwood Festival of Speed, this new (and we use that world very lightly) XJR 575 is the most powerful version of Jaguar’s flagship saloon to date. "I found out the mayor of Detroit had a tougher problem than I had as president of Ford," Miller said in a 1998 interview. "He was short of money, short of time and short of qualified people. We really didn't know how to help him." Customers wishing to opt in for the Huntsman pack will benefit from extra bed space for dog boxes and lockable storage space for firearms. The Huntsman D-Max is available in three paint options of green, black and grey that have been designed to blend into the shrubbery and avoid spooking game. This was also an era, don’t forget, when the green brigade began its inagrual march for fuel efficiency. But unlike today, when it's all about downsized engines and hybrid technology, in the late 1980s the buzzword was aerodynamics. And with its thoroughly modern lines and flush-fitting windows, the Cavalier Mk3 boasted a slippery drag coefficient of just 0.29 versus the Mk2’s 0.37. Overnight, it had made every one of its rivals look faintly prehistoric. As standard, every X2 will come with BMW's iDrive infotainment and navigation system presented on a 6.5in screen (although that can grow to an 8.8in touchscreen if drivers select an upgraded set-up). The system is similar to that in the new 5 Series this year and can be had in conjunction with an optional head-up display, which projects speed and navigation instructions directly into the driver's field of vision.
