I bought my 2011 TL SH-AWD in March and absolutely love it. I waffled between the '11, an A6 and a Lexus and Acura won me back on value and previous experience. You just can't beat the overall value of this car -- the features, quality and price.
I find it odd that many folks decided to buy a TL based on the updated 2012 styling. Granted, the 2011's styling isn't for everyone but it is distinctive, daring and unique. In black, my car looks stunning. The 2012's styling has completed gutted the car of any distinctive quality. It looks like an RL with a bit of Camry -- boring, no visual "growl" or sex at all.
