I traded in my Taffeta White 2009 Honda Civic Si for a Space Black 2013 Hyundai Elantra GT and I couldn't be happier.
Although I loved my racing header and exhaust on the Si, I love the way the GT sips gas and it'll probably see no such performance upgrades in its lifetime. What I am planning on doing is style upgrades, handling/braking/suspension upgrades, as well as DIY speaker and electronics upgrades. I posted a few pictures here in an upgrade thread so that we could all track Sub Mariner's progress.
Only 2,000 miles currently, let's see what we can do with this thing.
