Haha it's a bit hilarious you have a Disco, condolences. But you knew their reputation and wanted whatever it was you got out of it, and like most of all cars these days they just go and you do the scheduled service and all good except a couple of niggles. My BMW had 365k on it before I pulled the donk. It never let me down. Shit just started wearing out. They totally deserve their high ranking which has always been.
Anecdotally, old mate next door has a V8 Disco, bit older, he's a fuckwit so we don't converse. They only bought it not long ago, he's actually a used car salesman. It fucked up and was gone for a few weeks. They got it back, seems OK now but it had afew times not starting well and they opened the bonnet, did something and it went. Sounds col though. 100% why they have it.
