If i ever had the very, very weird notion to place a wine glass emblem on a car, it would be on a car like a Bentley or a Jaguar. Ya know, at least something with class. Putting a wine glass on an Alero...........................that's more like admitting you drink your wine out of a box. If you really wanna go with a "wine" motif, skip the glass and just super glue a "wine cooler" bottle to your hood. It would make more sense.
