Why am I having such a job getting a Jive Blue touch up for the 500?

All of the dealers seam to think it's not available, which if true is a really poor show by FIAT>

go to a prope paint supplier. they can make one up for you and it will be the exact shade of your car.

there are many shades of a colour and a touch up from the dealer would only be the first shade on the chart.

forget the dealers and get to your local paint supplier
