Soooo. Helped recover a friend's Merc amg e63 on my trailer a couple of days ago. He thought he had a flat battery as it would not start or turn over. Bits of metal in the cylinders and oil filter confirmed it was seized. 63k miles. Mercedes have quoted him £48k plus fitting for a new engine!!!!! Oh and they will give him 8k for his engine in part ex if certain conditions met. Nice way to round off the week.... He is taking it to a specialist engine company who will rebuild it for hopefully a lot less but probably north of £8k easily
