First question , is any of the rebate dependant on going through Chrysler Financial ? A lot of times $ 500 is . So if you are getting your own financing you could be looking at less rebate . Second , what does on the clock mean ? Using the full rebate of $ 3 , 000 and your credit union rate at 84 months your payment is right at 446 . 84 months is an extra year but since cars are so expensive nowadays it ' s designed to help you have a payment thats closer to your budget . I ' d say do that . <| sep |> I will try and kick this off . Lets first decide what a good groundbased test stand would start out as 1 Torsion WireCavendish Beam ? 2 Teeter Totter Beam ? 3 Air Bearing 360 Degree Rotational Assembly ? 4 Something Else ? <| sep |> Every school system in the USA have their own rules . I guess we need a few hundred different militaries that we do not have yet .
