I have, once. Last year when there was a bit of confusion about when production started, and which cars were produced in what order, I added a couple of sentences to the "Production" section of the Roadster page. Here they are:
"During the first two months of production, Tesla produced a total of three Roadsters (P3/VINF002, P4/VINF004, and P5/VINF005). Production car # 1 (P1) and P2 were built prior to the start of regular series production, which began March 17, 2008."
