2009 Chevrolet Impala LTZ

I have 2009 Chevrolet Impala LTZ 3.9L V6 for sale. I’m selling it for $3500. It has 168 500 km on the odometer. It is a rebuild and it also has the check engine light on which is thought to be a malfunctioning O2 censor. The hood open censor is also malfunctioning due to the censor having been spray painted during a repair (the hood closes properly). There is a leak in the air conditioning system. There is a dent in the right rear bumper as someone hit it in a parking lot. The car has been driven by an older lady who mostly drives it to the grocery store and back for the last 12 years and parks it in a garage. It has winter tires with a lot of life left in them. The summer tires are available for an additional cost.
