I also ran this same question threw my head before i ordered my whipple! i just couldnt bail out on all the mods i already had on my cobra! and i wont pay dealer mark up on any new car! ( complete BS) I have heard rumors of 10k-30k mark up on the new shelbys! they are going to be rich boys toys if this is true! my cobra books for around 26k and i got 10k+ in mods and i still get just as excited driving it today as i did the first day i bought it! i will look for a used shelby in 3-5 years once the cobra is paid off! by the way! my new whipple is just what the doctor ordered!
