ok, just as i thought...even YOU can't tell me what you get for the $8265, which is saying a lot, considering you jump to "defend" any criticism of the Regal in any thread...as i said, they are essentially the exact same car...a Camry is much larger than a Corolla and a 5 series is also much larger than a 3 series...your comparisons are not valid.
They both use different platforms, the aren't the same size as Flinter points out, they ride and handle differently based on preliminary reviews and they are priced according to the classes GM is targeting. Are those differences huge? Probably not. Are they enough to justify the price difference? For some yes, for others no.
I have been using other manufacturers as examples, but you persist in ignoring the point. GM is not exceptional in this at all. You can do spreadsheet comparisons 'till you're blue in the face, some people will still pick a midsizer, some the entry level car, regardless of how
you rationalize their decision.
Further to Flinter's point above, the A6 is available with the 2.0T in the US, but not Canada. So why would someone bother with the $42k 2.0T A6, when you can get the $33k A4?
