HI THERE.. i just resently bought a near mint 1983 sx/4 eagle from the original owner. the car is loaded with every option available and comes with every pieces of documentation since new .including the bill of sale from the amc dealer .NOW . the owner claims that 1983 was the last year of production for those sx/4 with a production no. of around 2200 .is there anyway to verify those claims .i love the eagle and now have 5 of them . but i am in no way a expert or a autority on them i just like the look.. the way they drive and the attention we get wile driving them . we also have a 1968 javelin sst and a 1968 amx 390 and at cruise night we usually park one eagle and the javelin or amx side by side . and the eagles are peoples magnet wile nobody ardly pays any attention to the amx (go figure )but anyway i would love if yoursel or anyone could shed some light on those claims above . thanks.. yours truly PAUL . P.S .if i was closer i would get those 2 eagles you have on e-bay .not even 1 bid what a shame
