My first extended use Volvo was an 74 145 which I got to 364K miles over a 15 yr period and taught me the joy of not having car payments. In doing so I learned to repair things as they needed it and not let them go. I also rebuilt the B20E twice and did two clutches. It was sold off with a frozen pilot bearing. Its replacement, a 1984 245TIC was purchased with with 200K miles and driven over 5 years to 340K with only a head replacement and turbo cartridge replacement, not even a clutch replacement. It was sold at 340K for $200 less than paid for originally, currently the economic champ. My current car is a 1989 745TIC that melted #1 piston and hence was rebuilt at 185K shortly after purchase, a bad choice in mechanics (Keith Taylor Motors, Mooresville,NC) required a main oil seal replacement at 205K (did you need that little coil spring too?) but hopefully is now in tip top shape. I would like to get this car over 400K after this mechanical work as I have replaced the headliner and brought the suspension to an ideal state with swaybars, Bilsteins, and upper and lower braces, all of which I reccommend.
