The TL is an older design which just about to be replaced in a couple years with an all new model that will feature the SH-AWD system. Most of the reviews I've read on the TL mention the fact that it has way too much power for the front wheels and torque steers like crazy. It's like any Acura, reliable, easy to live with, and boring as hell. It's based on the Accord platform, which is a fine car but it's really more of a 'near-sports' sedan than a true sports sedan.The G35x was just refreshed for 2007 and is based on a higher end platform, the Nissan FM (Front-Midship). This is the same platform used for the 350Z and the awd system is the vaunted ATTESA E-TS. It is much more car for your money. It also feels much more like a luxury car, with the interior aluminum panels modeled after Washi paper. It's a true competitor for BMW with its inline layout and performance oriented chassis.The Acura has better gas mileage and a better nav system. The G35 is better in every other way except price, but if it were me, I'd rather forgo options than get the TL. As for being a better buy, if you consider resale value I bet the two cars have a similar cost of ownership. The G35 coupe has topped residual value charts for a few years now, which is a good proxy for desirability.Avoid the Maxima at all costs. It's like a bigger, heavier TL. The Maxima has zero ability to manage its monster engine and will just try to kill you when you step on the gas. FWD + > 250hp simply do not mix.
