Eddles -

I have airtabs (see here), but I can't prove that they help.

Mine are designed for the end of truck trailers, i.e. boxy-ended shapes.
My advice is that if you have a boxy car like a Honda Element or a Jeep, they could help :

If you search this site, you will be able to find lots of "DIY" vortex generators that will keep your wallet plump and happy.
