Peeling, purple window tint makes a car look tired and messes with your visibility at night. Dealing with professional removal and a fresh application isn't the biggest car bill you will ever face, but timing it right matters. Scheduling the job during mild spring weather keeps the adhesive from drying too fast in summer heat or failing in winter cold, which usually keeps shop labor rates steady and fair.
You can often save a few bucks by calling independent tint shops directly rather than going through a dealership. Ask if they charge by the window or flat-rate for the whole car, and make sure old glue removal is baked into the initial quote so you do not get hit with surprise fees when you pick up the keys.
Remember that the 18-month 0% intro window on purchases is a hard deadline, not free money. If you still have a remaining balance on the Citi Simplicity® Credit Card when those 18 months are up, interest kicks in on whatever is left over.
