Chrysler 300 base starts around $24k with an underpowered motor. The Dodge Magnum is about $1k cheaper and a wagon. 300 availible in April with Magnum following a month later.
There were talks of bringing the Dodge Razor concept to the public. RWD, SRT-4 motor 2-seater for under $15k. I haven't heard anything since the 03 auto show.
There are trucks as well. Dakota is avilible with a 4.7L V8 and a stick I believe. Big discounts on Dakota with a new 05 model coming.
Best bet is an 03 or 04 Mustang GT which can be had for under $20k around here. Want better suspension? Upgrade it for cheaer than it is to make most other RWD sub $30k cars as quick.
