Well I posted in another thread about the good service I got last week, but it's worth mentioning again here.
The Vito needed a new windscreen, and ended up with a non-MB one
After which the auto lights didn't work (they came on all the time with the knob on 'auto'). Windscreen company said "book it in to a dealer - needs calibrating on STAR. We will reimburse you".
Booked it in to Rossetts Commercial in Aldershot, and while it was there I gave them a list of other minor things that I wanted sorted under warranty (slight rattle from driver's window, whine from Audio 20 head unit, false readings from front NS Parktronic when wet).
Got the phone call at about 4PM saying they had sorted everything apart from the windscreen - they were going to have to fit a new sensor module and they couldn't get one till next day. I said that really we needed the vehicle back, so they said "no problem we will send a tech. over to your house to fit it later in the week". We're not exactly local either.
Tech. duly came at a convenient time, and all sorted. Best of all - no charge, for any of it. So no faffing about reclaiming the money for the lights from the windscreen company, even though I'd explained about the replacement screen.
Rossetts have been M-B Commercial Dealer of the Year 3(?) times running - I can see why. We didn't get the van from them - in fact they've had nothing from us so far. It's been there twice for recalls, and once for a service (under service contract).
