Not sure if anyone else might be interested but I have been searching for exterior door handles on my S3 and none of the U.S. based Lotus suppliers had any options. I learned that the door handles from the S3 are shared from an Austin 1100/1300. So I looked around for some Austin parts and I found this website. http://www.austin1100-1300.co.uk/
They have new old stock exterior door handles that are for the S3 for only 20 pounds each. Both handles, with 1st class shipping to the U.S., 48 pounds. Much better than the $300+ I would have paid for rechroming.
