I have a 2004 Volvo XC90 with 103,000 miles on it, and would like to get another 100,000 miles out of the car. I have recently developed an oil leak, and took it to the dealership meachanic. They wrote it up as having 24'issues' including front and rear cam seals, hubs, flam e box and vvt solonoid. They quoted me $2727 to fix, but said I will likely have problems again anyway. Or they said I could replace the engine for $8,000-10,000. The car is not even worth that much! What do I do? I can't afford to replace car, or engine. Can I keep driving it and just add oil? Is it dangerous? I frequently drive from NC to NY or FL... is it safe to drive such long distances in the car now?
