Being realistic, there is a good chance if you collect it with more than about 2 miles on the clock that at some point it has been driven by the dealer/lease company staff, even if just moving it from one part of the compound to another or a mile up the road to the handover point.
They almost certainly ragged it.
Rag it, if it suffers a loss of performance in whilst you own it, claim you ran it in and get it fixed under warranty. :wink:
