i actually was deciding between those two cars slk55 and viper...and decided on viper, i will be purchasing mine as soon as i sell the xf.
but as far as the crossfire being popular in the kc area...very true...i have business in overland park every few months, and i see about 5 a day, along with 5 porsches, and an exotic every day...take the 20 minute drive from kc to opt and see what i mean.
