I'm not bothered at all by the size and weight of the car. Heck, it's only 150lbs heavier than the SN95...and look how many more options you get and how much more solidly built the car is. And I'll take the longer and wider wheelbase and more rigid chassis over the choppy ride of a shorter, springier wheelbase any day.
Yeah, chopping the size and weight and removing all of the options would make it quicker and more nimble, but IMO an over all less fun car to drive. You aren't always going to be pushing this thing hard into corners and from light to light. In fact, 90% of the time, you're just going to be in it enjoying the driving experience.....so why not actually enjoy it?
My Fox is all of those things that many here wish the new GT was and although it's fun when pushed and in comparison to what was available "back in the day" it's pretty decently set up....it's barely entry level by today's standards.
If owning a VASTLY better car means I have to sacrifice 2/10 in a quarter of a mile, or 0.3G's on the skidpad (even though the numbers still blow the doors off of any Mustang prior to it), then so be it. The trade off is well worth it!
