I like the Sixteen but I don't think it would cost $350,000-450,000, it would probably be more like $600,000-800,000 (I think the Bugatti Veyron costs 1 million). The Sixteen is America's answer to the Bugatti, but the Sixteen
V will leave it biting the dust Ha Ha!!!
It would also be nice if there was a hybrid version of the CTS/C, STS/C, DTS, FTS (Fleetwood), ETC (El Dorado).
V-Series=Hi-Po
H-Series=Hybrid
Also maybe an awd CTW wagon to compete with the 5 series wagon?
