My LR Discovery history
200TDi engine seized
300TDi brilliant for 150k miles
TD5 mk1 - engine hydrauliced at 12000 miles on the way back to the dealers the day after it had been serviced due to a misfire every time I went near a puddle. I couldn't possibly say that it was the dealer failing to put the air filter intake back properly that caused the water intake after driving the nearside wheels through a puddle, after all it was inspected by LR to say it was fitted correctly. The fact that it was the same chap that did the service and the damage inspection was pure coincidence. £14k for a new engine!!!!
TD5 mk2 Brilliant for 159k miles
Discovery3 - rejected after 6 weeks & TD5 returned
Discovery 3 (a different one, a year later) sold at 12 months due to 6 new headlamps, 3 radiators, 1 suspension pump and the thought of the warranty running out.
They are great when they work, the TD5s at the time were a similar price to a mondeo estate but had much better residuals so were actually a sensible buy. The 3 went into a different league price wise.
Still they were a bit more watertight than the defenders Ive had.....
