It is getting harder and harder to find car with a clutch. New cars come with double clutched auto trannies allowing the owner to use the automatic or shift gears without a clutch pedal. The shifts are faster than the old manual method and have fewer moving parts - no clutch pedal, no hydraulics, no slave cylinder, etc. It just takes time to get used to it.

The Four C air ride is an option on the Volvos. The first owner probably ordered it for Sweden pickup, the clutch was not on the list of options in the USA for 2005.

I liked my 5 speed 850, except I would forget to shift into 5th on the highway. It was really smooth.

Keeping it running is better than buying new

You might try a Swedish web site as European cars are much more likely to have manual transmissions.

Kelly blue book lists a 2005 Volvo T5R model with a 6 speed transmission - some R model cars have had their Rs stolen.

A dealer can run your VIN number to tell if it is an R model or what model it is.

I think that you can buy a replacement R from IPD. I think that this is because of thefts.

I owned a '96 855R for 11 years, and smiled every time I drove it, sometimes I sang!

BTW - your car might be quite valuable.
