Usually, if offered the same model but two versions (one Sport & one Standard) I got to confess, more than likely purchase the Sport edition.
This decision, I shamefully admit is more than likely due to the idea of "exclusivity" and should I say... the packaging, I'm a sucker for the care & attention lavished on these models.
Got to admit the box looks smart, but crap for displaying
Seriously though, it's not bad at all, it just takes up room when on show.
Anyway enough of these *gulp* collector thoughts and onto the cars...
I really think the performance difference is marginal; also the idea of longevity is a mute point. I personally feel you would need to put a lot of miles on the clock for the mechanical parts to really wear & break on either model.
Regarding overall performance? I doubt there is any real difference in reality. People have previously mentioned both types have each out-performed the other, more often the STD edition being the quicker (ironically) of the two types - although not by much.
Let us know which one you choose, either way I doubt you will be disappointed.
