■ Gearbox: Any clutch slipping in a manual car will confuse the “XYZ” speed sensor, causing the parking sensors, speedometer and reversing lights to fail. Self-canning boxes can often be treated with a full fluid rinse, but you should also check that a tired heat exchanger does not allow coolant to enter the transmission itself.
■ Brakes: Check the parking brake: dirt and grime build up in the drum and can block it. There is a manual release cable in the center console, but proper attachment means that the actuator must come out. Braking performance can be negatively affected by the oil in the servo, therefore pumping the pedal on your test drive.
■ Suspension: A yellow light indicating a car with a downward pointing arrow is a sign of a problem in the air suspension system, often accompanied by a message telling you that the driving height selection is not available. Compressor pumps, height sensors, valves and tanks are available but are not inexpensive. If none of this happens, an air shock has likely split and the entire unit will need to be replaced.
Also worth knowing
Companies such as JGS4X4, Celtic Tuning and Alive Tuning offer ECU remapping packages for TDV6, claiming an increase of around 20% in power and torque, as well as efficiency gains. Be wary of undeclared changes and notify your insurer of secondary market upgrades.
How much to spend
£ 4,000 – £ 5,499: Cars with high mileage in the entry-level S and GS versions. Some with manual gearboxes.
£ 5,500 – £ 6,999: Mostly cars from 2006 and 2007 with complete maintenance histories and leather interiors.
£ 7,000 – £ 7,999: High-end nightclubs in HSE finish with only a few owners on the logbook.
£ 8,000 and more: Run-outs with updated front and color coded trim.
The one we found
Land Rover Discovery TDV6 HSE, 2007/07-reg, 148,000 miles, £ 5,990: With heated and ventilated leather seats, 19-inch alloys and a panoramic sunroof, that’s a lot of car for £ 6k. Given the mileage, we would check how recently the cambelt has been changed and that the suspension and gearbox are still in good shape.
