Unfortunately the reality of the situation is that no one can tell you how long that car can last. I have a client that from the day he got the car has had performance mods on it that would blow most motors up and it's still running 11 years later with around 450,000 miles on it. And right now one of my techs is currently having to replace a prelude si's motor and that car is only 9 years old with only 85,000 miles on it. There are so many factors involved. Your best bet is to take it to your local honda service station and havethem do a complete inspection. it'll run you close to 150 bucks but it's worth paying that now then the $3,278.96 you'll be paying later (that's what this client is paying).
