Thank you, this is really great, gives me leverage as I'm talking to the dealer about it, it's a JLR dealer, but not approved used car and they're trying to fob me off that supercharger belt and spark plugs aren't needed, they've checked them and they're fine... According to their mechanic.
Is the diff oil something that comes up on the usual service schedule and is covered by usual service or is it like an extra thing? As in, is it due at a particular time or is it just when either the garage or customer says and then it's additional cost on that? And how often is that recommended? Thanks in advance
