I bought mine from the same eBay vendor last year. I have also bought a lot of other parts for the Boxster from them without issue.
This one is out of an '03 so it will work in our '01 to '04 986s. It is out of a cab with PSM so there is no issue with those lights. It is from a C4 but from what I have read on Pelican, this won't be an issue. Also, this is an Aluminum face (Code X71) which is rare and was an $855 option in 2003.
I bought mine from them for $250.00. I would offer the $275 and work your way up if they turn it down.
The install in pretty easy. Cost wise figure $60 for an oil sender unit $90 to reset the odometer.
