Well again this is all personal taste. I absolutely really like the tape removed on the black Sonics. You guys rock. I do like the black roof on the OPs car. I personally like some color on my cars though. (Remember Im a bit older and still kinda old school). Back then alot of cars were two-toned paint and chrome wheels. I still kinda like that.
---I had a Chevy (GEO) Metro with the tape on the pillars just like the Sonics have. My Metro was Victory Red and I removed the tape way back then. I didnt really like it much afterwards. I think I will leave the tape on my Silver Sonic. But seriously if my Sonic was black---bye bye tape.
I have also painted my bowtie on my old S-10. I never thought of using vinyl though (as another post suggests). I might do that, just dont know what color (for a silver car).
