believe it or not, the availability of the bi-xenons was a big part of what drew my wife and I to the CX-5 in the first place. We were buying a crossover for her, and she has bad vision at night, and we didn't want to spend more than $30k - the Mazda was the only one that offered them at that price point (and it didn't hurt that we liked the rest of the car too!). You can get them on the Santa Fe Sport and Forester, but they require very expensive packages that push the price well into the $30ks.
I would say the $1600 Mazda tech package really is worth it for the xenons alone. They're brighter and better than we had even hoped.
