Those looking for a model with sporty styling that still says luxury in all the necessary ways are going to love the 2012 Infiniti G convertible. While it may not be ideal for toting around all your friends and their mothers, Infiniti of Tucson thinks the new G is perfect for a bit of solo-driving indulgence. Of course, the luxury model does have a small back seat offering so if you have a little tike in tow, that's quite alright as well.
