I just wanted to share my experience with forum member, bigEC, who owns Elite Signs and Design for anyone interested in doing vehicle graphics and or vehicle wraps.
Recently Elite Signs and Design printed custom, full color EFI Logics logos for my 135i and they turned out flawlessly! I sent them an Adobe Illustrator file of the logo and they were quickly shipped to my door with extra vinyl pieces included just in case for no extra cost. Eric, bigEC, helped me determine the optimal banner size in order the image wasn't distorted after printing, quickly shipped them to me carefully wrapped to ensure no damage occurred during shipping and offered to guide me through applying the vinyl.
Located in New York, Elite Signs and Design can also do banners, building/office signs, installations and they guarantee their work.
Check out some of the work they've done.
