That link has a ton of automotive emblems in EPS format. I don't have a vector graphics editor on-hand right now so I cannot confirm it is what you are looking for, but check it out. Let me know if it is because I'm going to download them all if they are vector (they should be as EPS is a vector format).
I have been using Sonic Foundry's Vegas Video for a couple years now, latest ver-3 it simply rocks, very intuitive and powerful. Premiere gave me a migraine. If a user cannot do rudimentary things within a short time(<1 hour) then I question the value of that program, nothing like reading a 400 page manual to learn how to do something simple. I'm sure Adobe has its good points, but I have deadlines and don't have the time or money for classes.
