The sheared bolt.
Is it a cylinder head bolt or a manifold bolt/stud in the cylinder head?
If it’s a manifold stud then that may explain the initial diagnosis of a manifold problem. Remove manifold, replace any defective studs, refit manifold with new gasket. Not expensive parts, costs mostly labour. Don’t see how that would cost £700.
Possibly garage offer you poor trade in value because of the “problem” then fix it for peanuts and sell it on.
