Yes reallyReally? Depends what you mean by a 'major' service I suppose. There are 1 year items, 2 year items, 3 year items and 4 year items. I would expect major to be the 4 Year version. That is not £1000
As above, I understand the only difference in 2 year and 4 year is the (optional) lambda sensor and carbon canister. A quick google will show a number of independents offering a minor service for £6-700 and a major from anything upwards of £1000.
But don't take my word for it .... why not ask any of the independents who sponsor this site what they charge and what they do vs MD.
