I have a 2005 Crossfire Roadster and there is clean looking oil dripping out from behind the passenger side rear wheel right next to the fuel filler overflow tube. Could this be hydraulic fluid from the convertible top?

 

That would be my first guess. Ht the button, raise the rear window and lid and STOP - look down in there and see if you see a leaky cylinder.
Just remember that after nine minutes, the pressure is released and all cylinders will relax - so finish moving the top within nine minutes, but you have time to take a look down in there....

 

The fuel filler tube is on the passenger side and the top reservoir is on the driver side. Possibly a leaking top cylinder on the passenger side.

 

Thanks for the info guys.
