|Bottom line|| |
Although not as hard-edged as some sports cars, the 2011 BMW Z4 sDrive35is provides plenty of driving fun and, except for the lack of cargo capacity, makes a fine daily driver.
The 2013 BMW Z4 sDrive35is is an expensive toy with great power and tech, but at this price we'd recommend that driving enthusiasts choose the Porsche Boxster.
If you want easily accessible emergency services and like the idea of having a real person on tap to help you pick destinations, OnStar FMV may be worth a look.
At less than half what you'd expect to pay for a standalone device, the PLX Kiwi Bluetooth is a great OBD monitoring solution for the Android smartphone-toting car geek.
Featuring excellent fuel economy and a generally comfortable and easy-driving character, the 2013 Mercedes-Benz GLK250 makes for a useful all-around vehicle, good for the daily commute and family road trips.
