Derek,
You talking about the P2 service.
I managed to get it down to £140 with my own oil. Some of the dealers (in fact a lot in a chain) around here wanted £230 upwards, so pays to shop around, knock a bit off then ring the next one.....
Yeah, P2 service. I only paid £92.80 for the P1 service providing own oil but know the P2 service is more expensive.
