..if you are buying it outright then that BRZ is the better deal hands down...barely broken in too. The few problems the early models had were sporadic, there are plenty of users here with '13s without any problems. i had a 2013 frs (automatic mind you) that went to nearly 60 K with no problems whatsoever..admittedly my 2013 did have 2 interior panels that rattled and while i personally don't care for such things it is worth pointing out that the newer MYs (my '16 included) seem to have less rattling.
..if you are financing especially for 0% APR then I think a new 86 would be the better buy and as @
tobin mentioned it might be worth checking a PP BRZ too. The refresh has enough improvements to make it a good consideration versus the pre-refresh
