tamiya mugen s2000

first of all...is it a good kit?

what's the difference between the regular s2000 and the mugen s2000? just the wheels and the hardtop?
is the regular model better than the mugen in any way?

and is the hardtop removable?

does anyone have completed pics of it?

thanks.
i want an s2000 kit, i'm just not sure which one to get.

Read my review in the kit review section, it is on the second page. In short, get the Mugen one. If you want to know why, read the review.
