Before I vote, I'd like to ask what you mean by "cosmetic modifications?" Is it something you add or change that is not period correct, or deviates from "Z-ness" or just something that keeps with the Z Ness, but just isn't the stock or oem parts or design? About the judging- I think that daily driver, being over the usual 7 years old (when you are expected to trade in your "old" car to buy the newest model) could be 'divided' into a class that is older (25+years) and one that is newer (less than 25 years.) There are more parts available as replacements or customizations for the more recent models than the older ones, and the older ones are at a distinct disadvantage. For example, if you try to compere a 300ZX with a 240Z, you will probably lose because the 300ZX has all shiny new parts, and the 240Z has parts that have been repaired, restored, or from the JY. Another reason to try a split in the DD class into two similar ones is that because daily drivers, being say 30+years old, will most likely have replacement parts on the engine, (injector connectors, fuel rail, alternator, etc.,) on the body (body side mouldings, emblems, bumper parts, and anything rubber or plastic) and especially inside (carpets, seats, dash cover, shifter, steering wheel, etc.) That way, there is a class you could enter your low-budget DD and probably compete against the DD prepared by a person with a larger bankroll- especially in these current times when money and jobs can be hard to find, but not the enthusism.
