Assuming you have the 7 speed DCT auto & you think that the drive is not dis-engaging properly when stopping?
The gearbox should dis-engage the drive completely, Getting it checked out by a dealer or an indy would be my first move;)
This add appears to be the same car originally up for £29995 now being advertised at £33500 as a private sale, I would guess by the same guy as some of the photos are the same:)
Or has this already been said:(
Discs could be original:) will not be covered by the MB service plan:(
MB service plans are only good value when you add in any extras required (plugs, brake fluid, pollen/air filters & gearbox fluid) which are included:)
