This construction method - for old-school 4x4s, pick-up trucks and vans - is rugged for off-roading and load-hauling, but not ideal for refinement and ride comfort. It's also referred to as body-on-frame, referring to a separate chassis with attached passenger cell rather than a monocoque or unibody construction.
Like hiring a car on holiday, only for a period of years rather than days. Appeals to those who can't afford a new car, but want to be seen in one. You don't actually get to own the car yourself. See also APR, Contract hire, PCP. [See also: APR, Contract hire, PCP]
LED lights are more efficient and last a lot longer than normal light bulbs. They also illuminate more quickly, which makes them particularly useful for brake lights, and can illuminate to different degrees in response to the firmness of the brake pressure. Also used in many car interiors now.
When a car's rear end slides sideways as a result of you lifting off the throttle mid-bend. It's often followed by a trip through the local scenery or spin-off into the gravel if you're lucky, a trip to hospital if not. An experience known to many over-enthusiastic Peugeot 205 GTi owners.

A type of differential that allows each wheel to rotate at different speeds within a pre-set parameter. Cuts down on wheelspin in slippery conditions. Traditionally a mechanical torque-sensing (Torsen) system that works on the different torque inputs to each shaft, although new electronic, speed-sensitive, viscous-pump set-ups are becoming more common. Electronic LSD systems work in parallel with ABS to apply braking pressure to a wheel spinning too fast.
A single, heavy suspension bar that connects the two rear wheels. Often contains drive components such as the differential. Usually used in hardcore off-roaders and pick-up trucks as it's tough and simple. Cheaper than independent suspension to make, but not as good for either ride or handling.
Bi-fuel or dual-fuel LPG-petrol cars were popular for a while thanks to large tax breaks, exemption from London congestion charge and grants for converting an engine. Although said to burn more cleanly than petrol, this is now disputed, plus the cost of conversion now outweighs the benefits in most cases. Some owners of ultra-thirsty 4x4s, trucks and American cars still swear by it, but pumps are getting more difficult to find.
