Stock 18's vs Stock 19's
 

I have a set of the stock 18's for the G35C in my garage. I have some Volks on my G35c that replaced the OEM's. I was wondering, what the price difference between the oem 18's and 19's is? Because I want to change anyone who has the 05 OEM 19's FOR MY 18's and some cash if the 19's are more valuable. not too much cash tho. I bought my car a month ago and the 18's came off right away so they are completely new.
