ive been looking for a manual e46 to buy for several months now. I have found a very clean e46 with only 70k miles. The thing that worries me is that since it was barely driven it took 3-4 years to hit 15k miles on the car. Resulting, the carfax only shows that the oil was changed twice at the dealer in 7 years. I know the car has a light that says change the oil every 15k miles, but does it also correspond to time? The fact that the oil was changed every 3-4 years (unless the carfax does not show other records) is a huge red flag for me. I need some other opinions on this.
