Running in service is really important.The oil thats in the engine & diff is run in oil not meant for any more than 1200 miles,we had one in that had vanos issues & needed a rear diff because it missed the service & the warranty was void because this.The strupd thing is the 1200 miles service is free its included in the sale of the car so there is no reason it shouldnt have been done apart from lazyness or if its a import.
