I bought my car with 215,000 miles on the odometer from an elderly couple who used it for road trips. The interior & exterior is flawless, looks brand new ... Supposedly the "new" engine has 50,000 miles on it but its the original engine with new heads, parts, etc.... I've had numerous people check it out and says it looks good and should last a long time if I keep up with usual maintenance but is there anyway to check myself that these are recently added engine parts? I'm approaching 220,000 miles on odometer and getting a little nervous even though I plan on keeping the car. The tranny is original and I would like to do a trip to Canada with it. Any insight?
