2x6, I looked at the prior model of the TL extensively and briefly looked at the RL. It seems the TL is more car for the money - with a more roomier interior and more HP. That may have changed though, eh?
I thought the Infiniti G35 sedan was an awesome little ride. The Lincoln LS with a V8 and black leather was very, very impressive - big discounts on them right now, too. I thought the X Type and S Type Jags were pathetic and disappointing respectively.
