You're referring to leatherseats.com, which I said isn't as bad. Its right around where you said, 750-800$ for custom leather set. Katzkin is what he is referring to, which is very expensive. I have found OEM sets as low as 550$ on ebay, which isn't bad, but if I did want custom 750-800$ isn't terrible.
And I'm not quite sure why my thread was moved, I did not think this was tech related, since I wasn't asking for advice on how to install or change anything, just suggestions on quality upgrades.
Still wish someone knew about a good Bluetooth/nav head unit I could use that wouldn't mess anything else up
And thanks for the suggestion, not sure what Dynamat is but i'll research it.
