I may be biased here, but the '13 Si is the one to get. The 12's are ugly and the interior is absolute horseshit, while the 14's and up have Honda's annoying touchscreen and ricer supreme rims. The K24 is a good motor, and you can get 230hp out of those things with just a downpipe, tune, and CAI. Some simple suspension work, people swear by Koni yellows and the 22/24 mm rear sway bars, and you have a quick DD that's also decent for AutoX. Only downside is that that car is still expensive, like 17-20k expensive which I don't get at all. Its a weird tweener in the performance compact sphere that doesn't excel at anything, so not sure why it maintains its value that well.
