You can setup any sedan to drive anyway you want it to drive. The main decider on what to get is how often you crash and local support.
If you are new and crash a lot get an Xray T3 2012 or T4. Both are great cars and can handle a ton of abuse. Most tracks have a lot of guys running Xray cars. They will help you figure out the settings and get up to speed faster.
If you are a good driver that does not crash often and knows how to set up a car....just pick a car that looks cool to you. All sedans on the market are equally competitive.
As far as "driving styles"....there is no such thing. Most cars and tracks have one narrow setup window that will generate the fastest lap times. Usually, a properly setup sedan will have a lot of steering, drive on its nose and the rear rotates to follow the front in a very controlled fashion. A lot of guys do not like that feel and change their cars to be more rear biased. This is almost always slower.
Basically there are fast cars (setups) and guys that can drive them...or not.
