Ended up taking her car and only averaged 32.xx overall.
Not too bad considering if I HAD to be in the car 10+ hours I'd choose hers over mine for comfort, head/leg room, A/C works better, and she has tinted windows so no in-car-sunburn.
If its a 3.8L, those are real good numbers for it stock. Maybe its a 3.1L? I bet it would get 36 or 37 mpg with a hot air intake on it. Mine was a 3.4L Dual Twin Cam GTP with a Getrag 284 5 spd and headup display and driver info system and 21 way seats. It got 32 mpg hwy, but that was before I came up with the hot air intake idea. A comfy car for a trip, for sure.
