The Buick Lucerne was most certainly built on the G-body. It's a more reliable Cadillac DTS (Deville Touring Sedan) with its 3800 Series III V6 and 4T-65E transmission. I have the 2008 Lucerne CXL. With a heated steering wheel, seats, remote starter, parking sensors, and air suspension - it's one heck of a car! I picked mine up in April with 41K miles in Dark Crimson Metallic for $4,000. What a value.
The Lucerne is a G-body: https://en.wikipedia.org/wiki/GM_G_platform_(1995)
The Lucerne is a re-bodied Cadillac DTS built in the same factory, on the same platform: https://en.wikipedia.org/wiki/Cadillac_DTS

A G-body Lucerne was made from '79-'83 in very limited quantities.

Well, actually there was; GM just continued using the previous letter designations:
