The facelift cars, post 2005 hold their price better. 6 speed, led rear lights, suspension upgrade and changed wheels. Only one model all with ML and Sat Nav. The latest maps available are 2017. Tax on face lift is £500. Bluetooth is phone only.
Little things i've had on mine, spiral spring (no horn) £300, power aerial not working £60 both DIY. I test drove loads before purchasing, they should be silent, rattle free and feel solid and secure. Every car I looked at had bonnet chips, must be the shape.
