Yes, your car is rare assuming it was ordered from Volvo that way (was possible but difficult because you had to wait a couple of months for it) or someone converted it. You will have to verify through the vin. If correct with vin, keep it!!! The automatic was standard, the manual was an option not mentioned.
Standard features included crome grill and accent trim (up to '85) Sunroof (every GL I have every seen in the U.S. has a sunroof, not an option on the DL until '90 when they dropped the GL package.)Tachometer, small clock, power antennae, 4 channel stereo with amp, leather or velour interior with rear map pockets, alloy wheels. Cruise was an option, not standard. Power mirrors, fog lamps, antennae down switch I believe were options only available on the GL until '90.
