Well, after 110,000 miles and 13 years, done the water test, and if anything mine was actually smoother than the top gear test!!, Ok i have got the 1994 Celsior with air suspension, which helps soak up a bit more vibration.
Keep going to sell the car, but just cant, got a very practical 2001 diesel discovery, 7 seats and all that, and really shouldn't keep, two cars, however the Celsior on a run produces the same if not better MPG, than the disco, and with petrol being cheaper than more economical, and all of this in near silence!
if and when i decide to sell the car, will put it on this site first, as its in great condition, and would be nice to see it go to an enthusiast.
