Believe it or not, at some point in the fixup process, the 3's do get reliable. It takes a few years re each vehicle but then it is just the routine stuff.I have to admit to being slightly nervous at present. After finally taking the time to fix the erroneous 'Low Coolant' warning, I have no warning lights or other fault messages on any of my three LR's. Something is sure to go horribly wrong very soon!
Mind you routine is alot more than on a Chev pickup or a Jeep, but the 3's and 4's are a lot more sophisticated.
Tahoes etc are just now getting independent rear suspension and four corner air springs - that is about 15 years after the 3.
There is a cost to being on the bleeding edge.
