What year is it? Even though any 90ish degree angle is good I'd say the older the better since some of the newer boxy stuff has unbelieveably low drag for what it is. For instance there are quite a few sites claiming the new base Tacoma has a drag coefficient of .36, which for a truck is pretty damn good, provided of course it's accurate. Offhand I'm pretty sure that a Sienna would be fine, but some of the stuff they're doing results in normal looking vehicles w/ impressive drag coefficients, and something as crude as a VG may not help something that's already optimized.
