I drive an SRT8 challenger 6-speed manual trans, supercharged, and get about 14-15mpg in town, 23-24mpg on the freeway. A bit outside the $3k price range... I'd think a Neon R/T late 90's (97-98) would be a nice driver and possibly in the right range. I traded in my '03 SRT-4 Neon with 66K miles on it. Averaged over 30 mpg on the freeway with it and about 18-19 in town. Was a great little car and would like to have one again as a DD if possible (for staying down in Louisiana for when I'm at work). Currently when I'm at work I drive a '76 F150 4x4 with a 390FE/C6/NP203/9" and get about 7.5-8 mpg with it, and it has dual 18gal tanks. Will get about 2 weeks out of one tank though as I don't have to drive far when I'm down here. Still an SRT4 would be a much better choice I think for fuel economy reasons!
