well piss fire and save matches, i just read this thread and i gotta say i'll stand by shmoo on his opinion of the scions being crappy, but to each his own to piss their money away! yes the diy cai is feasible but by the time you cuss and bitch about how much of a pain in the ass it is you could have worked a few extra hours at the local mcdonalds and made the 50 or so dollars needed to buy a cai and some other cheap pos off ebay!
