Ah, but the problem with that first source is that it's Wikipedia - any numbskull can edit that info (and I have, on occasion).

For instance, it states that the Crossfire shares 59% of its components with other Mercedes models. Hmmm, the highest "percentage" number I've seen, and have seen repeatedly, is that it's built with 39% off-the-shelf Mercedes parts, including the entire drivetrain. So, always take Wikipedia "information" with a big ol' grain of salt...

There's a classic clip on YouTube from the TV show "The Office", where Wikipedia is sited as the best source for all info, because everybody can "contribute." YIKES!
