I've seen much rougher cars than yours win at shows....keep on it....
Speaking of
there are alot of shows here in NJ that are rigged. i found that out when a POS 71 monte Carlo beat me out. it had no interior, no inner fenders, crappy paint job, rigged up roll cage, and it was a filthy thing at that. Needless to say I will never be going to that one again. its a click thing i guess
