First Disco was a 1997 Series 1. No major issues or complaints other than sunroof that would rattle like crazy when open. Was going strong until a minivan ran a red light and forced my wife off the road and into a large hydraulic utilities truck sitting in a parking lot. Insurance totaled the Disco. My wife and 2 year daughter were fine. Fortunate for the minivan occupants that my wife managed to avoid a direct center punch at 45 mph. I highly doubt the minivan occupants would have survived it.
Replacement Disco was a 1999 Series II SE. I had some electrical issues with this vehicle which left my wife stranded 3 times in 2 years. It was a certified used LR so a call to roadside assistance resulted in speedy tow service. I forced my wife to sell this and move to a 2003 Expedition...
Current Disco is a 2003 SE-7. This replaced the Expedition that my wife hated. It was a good SUV, powerful, space, but there was one in nearly every driveway. Wife wanted something different and longed for another Disco. I bought this used with 22K miles for 70% of the retail new price. It now has 57K miles and so far beyond standard maintenance costs I have spent $1000 fixing multiple oil leaks. The LR DVD player has been replaced 2x and is again not all that reliable but I have yet to talk to someone with a robust car mounted DVD.
As already stated these things are a love/hate relationship. A real pleasure to drive, very comfortable, surprisingly stable on the road, and out of the ordinary. They are really nice inside with the dual sunroof and multiple roof windows. Low points are of course the not so stellar reliability (usually minor bits), oil leaks, and of course MPG. Wife is averaging 10-12 mpg around town and it drinks 91
Luckily the Disco is used mainly for short hops to the store and school.
Edit - also forgot to mention tires. The stock GY on the 18" rims are ABSOLUTE KRAP! Switch them out for BFG AT or similar and it will transform the Disco. Unbelievable how much better it drives with decent shoes. Off road folks should trade the 18" rims for the 16" that you see on our 1999 Disco. More/better/cheaper tire options and better off road capability.
We are still really happy with the Disco. Given the current market and where it is heading I don't know if I will ever sell it. I might throw on a couple lockers and turn it into a off-road toy in a couple years.
