Owning a car means watching the finish slowly fade under sun, road salt, and swirl marks. A deep clean and paint correction costs about $1100, but shops get quiet in late autumn and winter when nobody thinks about shiny paint.
That seasonality gives you leverage on price. Settle on the work and final price with the shop first, then use an interest-free window to handle the balance without extra costs.
A 0% intro APR window is a firm deadline, not free money. If you still carry a balance after 15 months, standard interest rates kick in on whatever is left.
