Well, to start off with I have a RedCatRacing Tornado EPX. While searching for that car I also stumbled across Exceed's website. I searched awhile and found the Exceed Sunfire. If you look closely at the two cars there's really no difference, besides the color of the anodized aluminum, and some other components.
There's the difference. Now as in manufacturers I can tell They both have pretty good reputations, and offer a great deal of help if needed. So I would recommend if you do need a good starter car try one of these, you definitely wont be disappointed.
