Instead of paying for extras, choose a model that has them all thrown in from the start. Choose lipstick red instead of pavement grey and you'll shore up your new car's second-hand value. Brightly-coloured cars sell faster and for more money than dull ones. Safe shades are red and black. Metallics are good news, especially graphite, dark metallic blue and metallic red.
Dark green is in along with silver, but gold, wacky purples and yellows are definitely out.
Buy a current model shape. When a new model arrives, old models depreciate fast. Make sure your new car has a reputation for good build, low servicing costs and a desirable image. Buy the best spec you can. Avoid base models and dodgy special editions.
