C) None of the above. (hey, you asked)

Hey, I have Roman numerals.

They are only confusing to non-Romans.

See if you can get NONE on your plate. If they try to ticket you for speeding or parking violation, the authorities may think the vehicle had no plate & they won't know who to charge...

jlex.

I immediately thought (c) too ;)

You actually gave me the idea of 85 IXXI, do alot of people give you grief about the incorrect roman numerals?

No, most people don't even know.
They ask me what it means, and I have to explain the middle year Porsche part.
That makes me look like an expert.

When it comes to being wrong about the numeral sequence, nobody knows the difference.

I would like VIIV IXXI. Too many spaces, but it balances well.
Soon enough they will have to have eight.
