Just the mags. The Trend has an alloy and the Style has steelies with cover...
Just get the Trend. The Style is kinda pointless in the lineup , not sure what purpose it serves since the price difference is so small so just get the one with alloys...
I suppose for those who intend to upgrade their mags anyway, it's cheaper to get the style. Then again, those steel rims will also have a lower trade-in value.
