The 165 is a solid little machine and hours matter a lot less than how they were put in. You could have one with 3000 hours that's been abused and another with 8000 that was maintained religiously and the second will outlast the first by years. What you really want to look at is service records and the condition of the undercarriage. Beyond that I'd say anything under 5000 is pretty safe territory if the rest checks out. Got pictures of the one you're looking at.
