Barry Posted: 5/11/2011 10:42am PDT Read an in depth comparison last year of the BMW M5 vs a Cadillac CTS-V. The Caddy beat it by 17 points and did so for $26,000 LESS......enough to buy another car. I'll stick with the CTS and keep the extra bucks in the bank. A acquaintence of mine had an M5. When it went out of warranty he had to sell it because he could no longer afford the "routine maintenance." Just another reason to go with the Caddy.
