I put a box, filled with slot car stuff, in the trunk that would not allow closure. With about 3-4 inches exposed I drove off. I noticed a slight exhaust smell so I rolled down the windows. Bad idea, it brought in more exhaust than before. Driving slowly helped with smell. Driving faster with windows down was more fun.
This reminded me of my 280Z going down a hill on the freeway.
Ah memories.
