Spinelli and Farago talk about Cadillac's potential M5-beating 2009 CTS-V. Will it be able to "suck the doors off" the Bimmer as Bob Lutz says, or will it be an also-ran. And mark your calendars. The two will be hosting RPM on Maxim Radio, Sirius 108 tomorrow at 2-3pm Eastern. Be there or miss talking about avoiding carsickness on road trips. Or whatever.
