FWIW, area shops and the dealer wanted $400+ for our Alltrack. A place near me that would have done the tint for dealer charged $75 less for their premium grade 3M product.
As for worth it, it is cooler inside the car. It's got the carry stuff privacy our Outback and van came with. The $325 to get it more like our Outback and van still makes the overall car price reasonable. The total of current incentives, Alltrack with the premium safety stuff and wheels makes it sort of 80% some other vehicles at about .5 or .6 the cost.
