acr is definitely worth it. its only about 1800 bucks. the wheels alone are worth almost that much. plus you get the struts, sway bars, special badging and seats
to clear the confusion, the srt-4 came in the following colors:
solar yellow (2003 and very limited # of 2004's)
bright silver metallic(2003-mid-2005)
flame red(all 3 years)
black(all 3 years)
electric blue(2004)
orange blast(2005)
stone white(mid-end 2005, replaced silver)
there is also the commemerative edition, which is white with blue racing stripes, and some other visual enhancements, blue stichting in the interior, srt-4 stitched seats, etc.
acr available in red, black, orange, or white
