I'd bought the 0W-40 oil and 2 Mann oil filters for the '15 BMW 3 Series, which promptly got itself flooded in a freak rainstorm and had to be totaled. I ended up trading the oil and filters to my regular mechanic as payment (plus his labor charge) for the Buick's first OC on my watch.
For a long time after I traded that car, I had the HeatShield sunshade for the Buick Park Avenue. Nobody wanted to buy it, in person or online. It was too big for the Regal; I had to throw it away. The Regal's HeatShield is still in my closet -- it worked well for the BMW, but was a bit small for the LaCrosse. (Anybody interested? PM me!)
