RL=DTS=S=LS=7
Those are flagships of their respective car companies.
TL=STS (currently CTS in near future)=E=GS=5
Those are midsize luxury sedans from respective companies.
TSX=CTS(currently, BLS in near future on rwd Alpha)=C=IS=3
........................so what does this mean? In REALITY,
RL flagship will compete will XLS/XTS (Cadillac Zeta Premium RWD Full Size sedan) which if CTS MCE and CTS V pricing allign properly, this Zeta Cadillac should come in base price in high 50's to low 60's and option up into the mid 80's to 90's. SHOULD* is the key word. So if thats exactly what happens this doesn't concern me if GM puts a current 08 CTS effort into a Zeta Cadillac large luxury sedan (even if they should be doing an ultra luxury sedan instead

)
GMI Freakout alert (granted when I read this I got scared too, but after thinking for a bit, realized this post)...BUICK should have a sedan that size priced at naer 50k USD even though if Buick were where it should have been all along price/size/feature set-wise on par with Lexus, a 70,000$ USD Buick wouldn't be far fetched in Park Avenue Ultra trim.
