The V90 wagon would be nice. The below is what I would do with most Volvo's I have bought. It is pretty much basic things, but will lay a solid base to keep the car. I would find a solid local bone yard that has some old Volvo's, and a good local independent mechanic that knows the V90. Good luck here.
