If you want luxury and speed the CTSV is you best bang for buck....there's nothing else out there in your price range stock or close to stock competing with it...... I will say again that they are not low 12 sec cars out the box..... Prof's is nodded..... I vie seen them run and there nice but not meeting my personal needs as I want a weekend beast! The CTSV is pretty damn expensive to mod...get on there forums and check them out
If I was looking for a sporty sedan id be looking at getting one no doubt
