I have a V70 T5, 1998, with just under 120,000. Just about every rubber vaccuum line on my car has been replaced, at this age and mileage they are brittle and ready to replace. The door panels are not fixable as far as I know but i've been lucky and owned two 98 V70's and neither had the problem. The master window switch is a weak spot, but can be purchased new for around $100 or on ebay for much less-easy diy fix which I just did. If the abs module has not been replaced yet, it's way overdue-i think the abs module can also affect the cruise control and also the speedo. Check the archives for abs module or contact the expert victor rochia who rebuilds them for $125 or so. I've also replaced my radiator, my heater core, my steering rack, driver's side front wheel bearing, and driver's side cv axle in the last year or so. All things considered, still a great car.
