OK, I thought about washing and waxing but decided my 2005 Outback with 205,000 miles, CEL 5 codes P0174, 0420, 1155, wheel bearings shot, worn tires, leaking HGs, VC gaskets, power steering pump replacement leaking, brakes worn out, HVAC selector worn and not "selecting" (of issue since all the above mentioned leaking fluids that weren't trailing the car or polluting every place I parked, burnt off on the exhaust and made breathing a challenge in the car) was a car in need of a new car so I traded it in on a 2019 Outback Premium with 8K miles.
I'll do just about anything to avoid washing and waxing a car.
