We do not have any confirmed hitch fits for your 2008 Volvo C70 coupe. I confirmed this directly with Draw-Tite and Curt. Curt hitch # C11065 is a fit only for the T5 convertible model for years 2011 through 2013. I cannot recommend installing this on a car for which it was not intended. Since there are no hitch fits there are also no custom-fit plug-in wiring harness products for the car so trailer towing is not an option.
Also, there are no aftermarket roof racks available for it. This... view full answer...
