How much would winter service and a rear wiper motor cost at a landrover dealer ship and body got some idea had a quote for 800 including vat is this dear thanks in advance

There's no such thing as a winter service.
It's a 6 month 6k miles service, or 12 months, 12k service, 24 months or 24k, and so on.

The rear wiper motor is an easy DIY job, requiring minimal tools and about 30 minutes of time, oh and they cost as little as £35.

So £800 for an oil change, screen wash top up, brake check and rear wiper motor change is expensive.

I replaced my rear wiper motor for a pattern part - £37, it is a single nut on the wiper arm, undo the two torx screw hidden in the little 'handles' on the inside of the boot door cover, pop it off the clips, release the wiring connector to the motor, 3 bolts hold the motor in place, pop it out and in good old fashioned Haynes Manual way - refit is the reverse procedure!
