BE CAREFUL OF A LOW MILEAGE VOLVOS...i know....i had a 245 estate(before the omegas) bit younger than that...1t was a 1992 on a 'k'...and mint...once all the seals,belts,perishables etc had been replaced a loverly car...and it was no slouch....and you could get sooo much in the back 
It's not just Volvos, but ANY low mileage old cars. Deb's 1300 had averaged 500 miles a year when she got it, and the usual reaction was it must drive really well. In reality, it needed 4 new tyres, all of the clutch hydraulics, a new brake M/C, new wheel cylinders a damn good service and a new speedo cable before it was actually usable. The brake pads soon needed changing, along with the driveshaft joints and a new wheel bearing at 25,000 miles. That said, I bet there aren't many that had their first welding at 40 years old!
Mechanical things work much better if they are used regularly. Using them frequently is even better.
