I’d give the dealer the oportunity. I’ve seen a few occations when the dealer is cheaper because they have seen so many and can knock it out. Let them this estimate. See what happens. Independents are great if they know your make and have any special tools needed. Some times they are better and try harder. It’s a toss-up. The price sounds like it’s in the ballpark. Maybe high on parts listed. Ask the independent what kind of parts being used. Factory parts tend to be better. My opinion.
