2008 Dodge Caliber

Looking to make room in the shed this winter and would like gone. Around 130,000 miles, clean car, has a small dent on front fender, black interior, good mpg. Problem with car is it has an engine Knock that comes and goes when you really get on the gas! If you drive like a normal person, it seems to run fine. I have been using this summer to go from farm to farm with no problem. Selling as a Parts Vehicle so no one gets pissy with me if something goes wrong down the road!!!! Would recommend trailering the car, just in case?! Thanks for looking.
