2015 Honda Fit ex-l leather 192,000 kms

My wife had used this car for commuting from Mississauga to Ajax. Brakes fairly new, general tires are brand new 2026 will come with winter tires also fairly new condition Michelin X ice with rims. Interior is black leather. The car is being sold as is there’s an error code P0420 I will look it up tomorrow my mechanic looked at it, maybe six months ago he says the car works fine. He couldn’t find anything wrong with it. Just drive it. We’ve been driving it for six months. Has been no issues. There was an issue with 2015 Honda fits, and that was the injector issues. We changed the injectors about three years ago at a cost of $3000 to the new ones that have no issues. Other than that serpentine belt was done last year the body is fairly good no major dents or scratches on the doors of maybe underneath the rock panel a little bit on one side, not noticeable. We are selling this car as is so bring your mechanic with you.
