Especially with lack of tuning options. The base model has a lot of potential with the right mods but it will take a lot of time, money, and cursing. You would also need an alternate mode of transportation for when **** inevitable goes wrong. That being said I do love my boosted 2006 base model though. Even people that know what I have done to it still are blown away when they go for a ride in it. I didn't get it done without my fair share of troubles and she still isn't perfect by any means. If you want a project car to learn how to wrench on, the base model is an OK option. If you just want a faster car that handles better, can make some really good power with minimal mods, and not have to tear into the internals of the engine, then trading up to an SS is the route to take.
