What the current trim confirms is the chassis capabilities and the premium feel - equipment level and the build quality of the car. The powertrain upgrades will probably complete the car as a "premium sport sedan".
i agree...however, at most likely north of $40k, it better be, as it will be in a very competitive and solid bracket...the question then asks, will the Regal Turbo CXL,well equipped at $40k+, with its 220 HP engine compete well against other great cars in that price category...while i am sure the added boost from the Turbo will make this car "better" in terms of it being a "Sports Sedan", there is an awfull lot of good company up there...the 335i is $49k, and that is one heck of a ride...someone might think, "Hey, I'm already at $42k, a few more grand and I can get an Audi, BMW, Mercedes, Lexus, Acura, Infiniti, etc".
i mean, from the looks of it, even a Taurus SHO won't be far off (it's $43k right now)...bigger, badder and likely worth more down the road.
