i was due a B service on my 11 plate W204 and decided to go to local indie with decent reputation after previously using Merc ‘specialist’. Decision based on price and location. Wanted something between Halfords and real Merc. It had been mentioned on previous service that transmission service was needed but could not afford at the time. I also knew that brakes maybe an issue as warning came on 2 days prior to booking in. A lengthy discussion transpired after initial check - transmission oil never been changed over 80K miles. My fault for naievity on this. Front brakes were down to to a hope and a prayer. So my original £325 service was completed at a cost of £975. Mainly my fault for procrastination and nativity. It was washed and vacuuumed very nicely though. Just hope the missus doesn’t notice the next credit card statement - lots of Tesco points though?
