A few hundred bucks??? Just sounds like a minor cleanup is needed. I would imagine most techs would charge less than an hour of bench time to do this for you... If you say your A6 has issues you will probably have to come off more, even for a simple inexpensive fix like this.
Yeah, and if you can get this done locally, easily, it makes it more attractive to folks who maybe don't have that ready a tech resource. If the cost of fixing is less than the knock off price estimate, just go ahead.
Yep, I'd get it fixed first. I'm always skeptical if someone is selling something with known issues and saying they're easy to fix. "Hmm, if it's so easy to fix why haven't you done it?" So I wouldn't pay as much since the cost of repairs is unknown.
