Summary

Engine-related problems, particularly oil leaks and timing chain concerns (especially on the N20 engine), can be costly to address. Transmission issues, rough shifting, and electrical gremlins can also surface. While some issues are relatively minor and inexpensive to fix, others can lead to significant repair bills. Careful inspection and a pre-purchase inspection by a qualified mechanic are highly recommended.
