I had a brand new spoiler of Tony (DOO) in 2009 - i payed £300 for it and it didn't have the V as non 500 part but and it's a big BUT, for the time it took me to draw around the stem of the upper spoiler and cut out i wasn't bothered.
500 lower spoilers in brand new condition don't exist, well commonly on the market that is but if one came up i would bet my life it would have at least £800-£1000 price tag on it.
I had the chance of many second hand warped faded spoilers for around £200-£300 but decided on one of Tony's new items for the same money.
No brainer really if you are fitting to a non RS500
