I'm fairly close to finalizing the purchase of a 2016 Facelift Model S 90D. I'd like to find a nice set of lightly used 21 inch square turbines in grey (or even powder-coated black - not interested in silver). Located in Kansas; shipping to me is likely the best option. I don't anticipate tons of sellers in my area. Please send me a PM if you are interested in selling. Thank you.
