Here’s an example of the importance of cross-shopping:
The 2012 Infiniti G37 coupe – rear-wheel-drive, standard 330 hp V-6, seven-speed transmission and 0-60 in 5.6 seconds – starts at $37,800. For about the same money you could buy a Mercedes C250 ($37,220) and take home four cylinders, 201 hp and 0-60 in 7.4 seconds.
