I was told by a guy who was going to buy my evo ,( who himself had a couple of csl's , one of which he had supercharged and generally spent a fortune on it) that the running in service was a must below 1500 miles, as mentioned it affects the resale value, more so if its going as a p/x to a delaler.
Most relevantly though he said it was so important as , due to its nature, as in , it is a running in service, the car up until this service is completed is using specific grade "running in oil" in the engine and also in the rear diff.
Anything that has been driven hard after the running in period is completed, and has not had the fluids changed for the correct ones will basically be getting caned with limited protection for the load bearing (expensive) parts.
Hence the possibility of premature failure/wear on the engine and rear diff.
Could be total bollocks , but it makes sense.
