I wonder if they're still sticking with the 5W-30 Mobil 1 which IMO has always seemed too thin, what their oil temps look like after a lap, and as for Castrol SRF - I'd rather know the brakes have enough cooling not to need it.
As for the M5 vs CTS-V - they are the same market, I'm an E39 M5 owner, have no particular interest in an E60 M5 (don't like the interior on the E60 and I'm not fond of the latest buzz-bomb M motors), the last V was a nice mechanical package but the interior and general material quality was underwhelming (and anything with that limited rear-window visibility ought to have backup sensors), this one might be tough to pass up.
