That's a GL1000 LTD. Not exactly your standard GL1000 and quite rare. I've only ever seen two. One year only(1976), special paint, lots of gold anodized and chrome parts, different fenders, quilted seat. The fact it has only reaveled 1.8 miles and is unrestored probably adds to the high price.
Goldwings are a largely american motorcycle. They were made here in Marysville Ohio from 1981 till 2012. It is unusual to see an early GL1000 outside the US, esp in someplace like england.
