"Best" would probably be 2012 (oil cooler, other little bugs fixed) or 2013, if you prefer the different front fascia, wheels, and other little cosmetic refreshes. For the 2013 Nismo, same body kit, but wheels are gunmetal and its equipped with SS brake lines (if memory serves).

Most buggy will be the first MY for the Z34, 2009 (ECU whine, etc.).

That said, the best will be the one you can afford -- awesome sports car for the money
