Before you buy anything, jack the car up and inspect the wiring to the speedo sensor on the differential. The wires tend to fray near the connector causing the speedometer/odometer to not work. This is a fairly common problem and can be an inexpensive fix if you are handy. The wires will need to be cut and butt spliced together. I replaced the connector end on mine using the volvo connector end, heat shrink butt splices and Volvo pigtails.

Has the AC been retrofitted to R134a? If so and it only needs a recharge it should be inexpensive to recharge. Who diagnosed the AC? I tend to be suspicious of AC claims when acquiring a car without it working.
