T-Mobile is pants and they will merge with Orange soon and that's not much better so out of the 2 I would go with Vodafone but given a choice it would be O2 without a doubt far better than the others
I have a vauxhall Meriva 1.6, when i checked the oil level i have found a white/grey oily deoposit on the filler cap. The coolant level has not changed and the engine sound's o.k.
Can any one advise please.
