Land Rover Repair: TD5 Engine, hard shoulder, good shape

Question
I have just had a Discovery 2 (2002MY) Engine blew up on me. I've owned the vehicle since new it has 48K on the clock. Whilst driving we had smoke inside  and outside the car, and Engine reved furiously without customer input for a while. Even when we had escaped the vehicle on the hard shoulder. Lots of smoke from the front and back. The garage say it is a piston broken and deisel has mixed with the engine oil, metal has damaged the injectors and that it will cost 7K to mend? Have you heard of anything like this before and can you suggest a best course of action? I don't want to spend 7K on a 10K vehicle? What would you do in my situation?

Answer
I like Land Rovers so I'd probably fix it provided the rest of the vehicle is in good shape.  Only you can answer that.

It's almost always cheaper to repair your existing vehicle than it is to buy a new one.  It's true you are considering spending most of the vehicle's value in repairs but the alternatice is spending double or triple that some on a newer used rig, or four or five times that sum for a new one
