the_sigman, Maldonado is indeed the best ever. To be fair though, if it was operating under the old 9-6-4-3-2-1 or 10-6-4-3-2-1, then Maldonado would have finished higher than di Resta, Schumacher, Hulkenberg and Kobayashi.
Irishf1 has it. The only other 13th place for a race winner was Jimmy Bryan in 1958, although that was because of Indy so I thought it unfair to count that.
