Depends on the state. In Rhode Island that is true for cars, but not bikes. What a ripoff in the state of RI when trading in a bike (basically no credit for tax on the trade in).you will get more if you sell yourself, but if you trade for $6440 you will save big in tax on the new purchase.
I have a trade that needs tires...I see KBB is mid 5's. I'd pay 1k over invoice if they give me the 6440.if invoice is 10k why are u willing to pay 11k????? thats a full 1k over!!!
