Other than that LTD, I think I may have the longest car here. 1998 Chrysler Concorde LXi. Hooray for a 209.1 inch overall length, and a 113 inch wheelbase. It does have plenty of interior room, however, and I can lay in the trunk longitudinally. It handles like a big American car (understeer) but it actually grips pretty well. It pulls harder than people expect too, I've beaten my friend's 1993 Audi S4 a couple times. Had it up to 130mph before I chickened out (speed limit was 60.)
I'll get some pics tomorrow.
