I have a 1991 K75 RT ABS that is my daily rider. The reason I have it is I was wild about the BMW K bikes when they first came out, but didn't have the money. About four years ago I found one that struck my fancy. Tires, battery, taillight bulb and a clutch cable has been it in 20,000 miles with the one complete spine lube ordeal. A friend of mine had a R75/6 which he let me ride frequently and I found it pretty close to my Commando for a riding experience. It really floated my boat. Not nearly as much eye appeal as my Norton, though.
I see there's another similar thread titled Norton and Guzzi. The same friend with the R75/6 has now become infected with a Moto Guzzi virus (5 of them). I rode his 2007 Norge. What a wonderful bike! Of all the one liter plus sport touring bikes I've ridden the Norge is the hands down winner. That thing has the torque of a tractor! It also has a tremendous amount of eye appeal, to me, anyway. Big drawback to the Guzzis for me is the lack of dealer support. From what I see you are about in the same position as with the Norton, waiting on the UPS man. There is a Moto Guzzi dealer near me (sixty miles), but I think he has more bikes than total spare parts. It's usually a case of, "I'll have to order that for you".
I've pretty much decided that any bikes I buy with the intention of riding them much will have to be water cooled. I love the clean look of air cooled bikes, but when it comes to reliability, the water pumpers have no contest, for me, anyway.
I do like old bikes of most any make. Lately, have been having a desire to have an early Honda CB750. Saw a restored one at my local diner and it brought back memories of 1969 when they first came out. Truly a marvel. I had a T150 Triumph at the time, but I was envious of those big, fast Hondas. Come to think of it, a T160 (never did develop a liking to the bread box T150) would be a nice acquisition. It never ends. Does it?
