I'm thinking of selling my 71 chevelle and getting a gn/t-type and i was wondering what year would be the best to get? I want fule injection, and I don't know alot about buicks but didn't they start putting intercoolers into the gn in 86 or something? Also, is there anything i should look for in a gn/t-type other than the usual stuff.. i.e. frame damage...rust.? Thanks for any help.
