Unfortunately, Insurance is the only thing that I have not researched and that's the thing that I am most worried about, as you said, It's probably going to be my biggest hurdle. As for having a hood scoop and a spoiler, I don't really care about it too much, I just love the overall look of the blobeyes. Honestly, I think the WRX looks better without the rear spoiler.
The size of the car doesn't really matter for me that much, my dad has let me park and drive our 14' S-Max and that is quite a big car, I didn't really have any problems with that but I'll also take that into account.
So, the only thing that I will have to look @ is the insurance prices for a young driver.
Thanks for the advice, ScoobyGhost.
