I like the seats, but are you sure you want to have them in a silver car? This interior color is best paired with black or dark metallic red/green/blue. Silver cars look best with black or red interiors.
Thanks to a helpful friend in the UK, the MX-5 is getting a touch of luxury in place of the stock cloth seats. Shipping will probably be more expensive than the seats, as they cost just £30 and will only need cleaning, no repairs.
