The latest models.

Interesting choice of car to compare. While both cars r fast, the answer depends on what u r looking for in a car. Based on the two cars u have selected, l am assuming that performance is high on ur list of wants. Although both r performance oriented, they r quite different in a couple ways. The BMW is a rear wheel drive & the WRX is all wheel drive. Certainly if u r driving in a location that has snow or lots of rainy weather, the WRX would be the car l would like to have. However, if u live in sunny California or another warm, dry location, the BMW would be my choice. Also, if handling is important, l would give the edge to the BMW. Another plus in the BMW, would be the car is more luxury than the WRX. The WRX is lighter than the BMW, but both have an extra boost in power coming from a twin turbo in the BMW & the WRX is super charged ( l think, but l could be wrong)

It all comes down to what u like in a car. As for my option, l would give the nod to the BMW because it is a balance of performance (both power & handling) & the luxury touches.

Well, that is my 2 cents worth. l hope this helps.
