I currently have two, although they are Disco 2's numbers 2 and 3 for me (and landy #4, I had a Series IIa many years ago)... I have the D2 illness... although that illness is probably something very much like Stockholm Syndrome...
My first one was a red TD5 diesel which I sold after owning for quite a few years and over 100,000km, my new red one is a V8 and all I can say is it has about the same power for about 5 times the fuel costs. Sure, it sounds better but fuel here (in pre-covid19 days) was like $2.50 per litre or something like that, and with an 80-odd litre tank I just couldn't bring myself to drive it that much... so now its a pseudo-tractor and parts donor.
My daily driver / toy (and secondary pseudo tractor) is a 5-speed TD5 diesel facelift with a remapped engine... its a lot of fun to drive on- and off-road, but after driving this a lot with heavy loads I do wish it was an auto because the TD5 engine is pretty lacklustre below about 1800RPM so taking off with heavy loads or in boggy ground or sand requires a lot of clutch feathering - I've read a few threads on using the V8 auto on a TD5 and will probably go that way eventually since I have one sitting in the red truck - but that means I need to also find and fit a TD5 auto ECU - so I'll loose my remap... so I may just sell it and get Landy #5 :)
