I've been in a LR on/off from around 96 until just recently. Of all the Rovers I've been in, owned, or known, not a one of them left us on the side of the road. Most of all the repairs were normal wear/tear items, and of coarse the delicate interior stuff like switches or misc trim. Powertrain wise the 3.9L, 4.0L, and 4.6L engines never failed, nor did the the transmissions or axles. If you keep on top of your maintenance, and always give your LR a good inspection between oil changes or during you can keep from being on the side of the road.
Only vehicles to leave me on the side of the road during my entire life are 05 Jeep Wrangler with a P0700 fault that wouldn't clear hence it wouldn't shift..., 2012 Ford Transit Connect with several roadside visits from an idler pulley falling to pieces, 2 transmissions blowing up, and the electric fans dying causing it to over heat..
I have never had a LR leave me on the side of the road requiring a tow truck. I've had a front axle shaft snap on a 97 RR (after off roading), and I still was able to drive home, I had a coolant hose blow off after a LR Service Campaign (tech didn't tighten the hose & I saw the steam before it overheated), and I even had an old Lucas alternator go out on my 94 RRC but I was able to drive it home before my battery fully discharged. LR's will give you some signals or warning signs before they have an issue. You just gotta know what to look for lol.
Now is every LR perfect? Nope I've seen some LR's get to nearly 300K without any major tear downs (long distance travelers), then I've seen some LR's not make it past 20K (in town stop n go or just the day the German/Brits weren't getting along at the plant...) without having to have some serious work done.
I've now owned a total of 7 LR's (not an entire hanger full of LR's in Dubai sorry) and sure some interior luxury's died early or needed replacement like our lovely D1 auto dimming mirror for example, but I have never experienced any serious failures that left me for dead. I even have a 98 D1 parts vehicle with a serious engine knock (got it for 800.00) and the thing refuses to die!!! Cranks up perfect, HVAC works, locks work, windows work, transmission shifts smooth, brakes work, and the transfer case goes from H to L without issue.
