LOL, oh, go on, I can't tell you to go out and buy a nice new Camry or Odyssey or something equally boring?
Seriously, I'd try the
Chicco Key Fit,
Combi Connection, or
Combi Centre, or
Graco Snugride for infant seats (these have the benefit that you can leave the handle up when driving, which can spare you a few precious inches of front leg room), and if none of those work, I'd try a
Britax Roundabout, which is a
convertible you can use from birth and is notorious for easily fitting in most cars
rearfacing and
forward facing.
Good luck, post back if something works!
