We love (wife still loves Defenders more though :) ) the D4s ride and power for towing but at 6 years old now and having read so many horror stories I'm changing vehicles and have  ordered a Prado. Yes I know they without character etc etc and have their own faults, but maybe having to replace the Discos engine with some dubiously refurbished one from somewhere at enormous cost, does not appeal to me. Plus having gone down to one car as the wife no longer drives, that would makes things even worse.
I just maybe go for a D3OO Defender but can't really see another 50 grands worth of value in them. 
Here's hoping the OP gets his fixed at a reasonable price and ours last until the new vehicle arrives in maybe a year or so......
