Yes they come up on Ebay every once and a while. I expect by now they are getting pretty pricey BUT if this car is being keep for a collection, etc. I would say they are perhaps worth the price. If I remember they at one time sold for around $199 for the set. In all honesty they are NOT very useful in a roadster. They are not really custom made like the plder sets in the Mercedes, Bugotti, etc.

They were only given with a certain year. Maybe 2005 I'm not sure on that number? Someone will chime in with the correct years and also give their idea of the worth and dollar value.
