It's just a way tp lock you into a deal... If its on layaway, your gonna get that specific turbo kit when you get it paid off, if you had it in a back account, you could still be weighing the pro's and con's of all the kits, and maby by then, the NER will be on a few cars and be tested and proven... I just dont like people holding onto my money for months... i'd rather be the one holding, and buy the kit when the money is there...
