We bought two cars, Two sets of fronts and four sets of rears and the bill was $629 and some change (shipping wasn't broken out... just a total bill)... Essentially $630 for two cars with spare rubber for each. Having spent the cash... not knowing what to expect... I am delighted with these little stinky cars...
Again... right now... I think that my 1/10th with either the NR or the Collari motor is faster overall... but these are right behind in speed and are a blast.
