Dealer service history may carry some weight, subject to who the dealer is. When I bought my 2006 4/4 70th Anniversary it had a full dealer history stamped service book with every annual service done by the same dealer. I bought it with a fresh full service and MOT.
Within weeks I needed to change the tyres (age related) and the tyre dealer struggled to get the spinners off, they were so tight, the wheels clearly had not been off for years, I found the spark plugs hadn't been removed in years. One was rusted into the block and it took Matt at Life's all his years of experience to eventually remove the plug especially when the top of the spark plug sheared off. So much for the value of some dealers service history.
Whilst there are some very good home mechanics, I prefer to find a good reliable specialist service agent to perform all my servicing work, they have far experience than I have and most will undertake preventative maintenance.
