given that the servicing is every 2 years on these, I am just wondering if there are any items that should be checked by ourselves at least annually. for example, are they prone to needing a top up on engine oil given the big V8, etc? bearing in mind I am not mechanically minded at all! what do you guys look out for in general? I don't tend to do that many miles, perhaps 1-2k per annum only, but some of those will be hard driving
