This is what I have found on Amazon:

Mercedes part number for housing W0133-1607413-OES

Mercedes part number for cylinder W0133-1619200-FEB

Total price for both = less than $200

When I did the model search on the site for these two parts with the seller, it said "does not fit 2005 Crossfire", however down in the Q&A section it has people saying it fits their Crossfires. Anybody out there have any feedback?

Still unclear if the manual transmission vs automatic transmission plays a role with these parts. Comments?
