English speaker here to talk about the site?

I may have some questions, like:

What is the difference (sometimes a model exists in these two versions) between worlwide and without spec?

For exemple: http://en.wheelsage.org/honda/nsx/i/na1_1/

http://en.wheelsage.org/honda/nsx/i/honda_nsx/

:/ ?

I propose an idea to improve the site, it would be necessary to revise a little the arrangement of the models, what I mean is that it would be necessary to put the trim of the models, for example: for the ds7 crossback some trim are listed, like the Opera finish or the Performance Line finish, but there are many others of the style: Bastille, Rivoli, Business, Executive... But because they don't have pictures, they won't be listed on this site, but they exist

I propose an idea

It would be interesting to have the possibility to notify a user in our comment, a bit in the style of instagram, we would write @ and it would propose us our contact list ?

It is almost indispensable I find :)
