Metro makes great blowers and also vac's.

Although the 4hp vac n blo works great as a vac, I dont care for the flimsy hose for the air blowing. You pull the vac filter out, and then put the hose on the other end and then it blows.

I bought the Sidekick hand held and used it for a few years. Works great with coatings and a very well waxed car.

Last year I bought the 8hp dedicated blower for drying cars. I wish I would have in the first place. 30 ft hose blows garage out, driveway off, and also the cars. Worth every penny. Most of the electric or gas leaf blowers do not dry the car totally and leave water in the cracks and places. The dedicated Metro blowers will get all of that out. If you prefer to prevent scratches and do not want to dry a car with a towel, then get the largest one you can afford. Its worth it.
