I have some extra issues of the GSXtra for sale. (22) issues from the late 90's until present, PLUS (5) random issues for a total of (27) issues. MANY sets available. TON'S of tech and pictures, and many articles and features on many great Buicks and Buick people. $36 including shipping in Cont. U.S.
I have most all of them back to the late 90’s. I sell them in 27 counts due to shipping. They get heavy.
