The latest version of the Autotrader App is worth a mention as it now adds the ability to save your car details (not bike currently), which allows you to add tax, MOT, insurance etc dates and will remind you when they are due (a service which other apps including the DVLA charge for). It will also give you a current resale value of your cars, so I'm happy now knowing that my car has only dropped £3k in the last 3 years, but the missus car has dropped £5k in 2 years Auto Trader Mobile - Take your search with you anywhere, any time
