Their website is having a bit of problems right now.
Tell them that you are looking for vinyl side-graphics for your Toyota Celica from the "Long Beach Celebrity Grand Prix". From the 2000 - 2004 years. When it was driven with Toyota Celica. Before using the Scion tC.
They should know exactly what you're talking about and can help get you closer to exactly the graphics you're looking for.
IIRC, VinylMayhem has a long history of doing graphics on the 7th Gen Toyota Celica.
