My two cents: keep the Si.
You are not missing out on a '18 86. It's still the same car you had. Just has a new face. Unless you get the performance package, but even then it's just big break kit you can buy for the same price (somewhat the same)

The Si has more power, more room, more gadgets, and better comfort over all.

If you want the sport car experience, then get it. If all you want it for looks you can do better than a 86. Just my personal opinion.
