Please Help me answer some questions with Rims

Hello all, I've always wanted to get some rims for my car but never found the ones I liked. Until now. I saw Akuza Belle 761 (http://www.rimslegend.com/akuza--belle--aka-761-wheel-packages---akuzabelle) rims the other day online and I really like the style. The question is: would those rims fit my 2000 mustang? One guy told me that it would, a guy at Discount Tires said it wouldn't. what do I look for? bolt pattern? Please help.
Thank you for your time.

Yes, those rims will fit on your car. You want the 5x114.3 bolt pattern and either of those offsets should work (I might go 45 mm up front and 35 in back).

Don't go back to that discount tire, they clearly don't know what they're talking about and just want to sell you what they have on their shelves.
