Both are safe investments in that if you buy them at the right price and take care of them you should be alright. The way I look at it, the Cobra gives you more performance but at a significantly higher cost. The Fox is more affordable while still being fun to drive, but not fast in stock trim by today’s standards. It all depends on what you like and how much you have to spend. Either way you end up with a great car with a strong following.
Well said, thing about the Fox is it's an old school hot rod, while the Terminator is very visceral and responds well to mods while still retaining good driver feedback if that makes sense.
