I've been considering both cars. I like both aesthetically, and for the practicality that comes with a 5 door hatch. I wasn't even considering a GTI until I saw the potential power gains with just a stage one tune. Then I started pricing 2016 models, and they can be had used for about the same price as a 2016 focus ST. Most people agree the fit and finish is slightly better on the GTI. So why shouldn't I go with a 16 GTI? The only thing I can think of is the ease of maintenance/modability. Does anyone know which is easier to maintain/modify? Also, if the GTI isn't a pain in the ass to work on, why should I stick with Focus ST as being my top contender for my next vehicle?
