Ditto. Thanks for dredging that up, Metro.
I noticed they use "high quality" duct tape for their mods. Something we home DIY'ers can shoot for.
I tend to use black duct tape, so it matches the trim on my car. A real consideration, since my temporary grill block stayed on the car for six months.
IMHO, they are not hard-core hypermilers, though. I see they chose stability over low drag. Wimps.
Thanks again,
Stew
