'95 is the best year for an sn95 mustang...no i'm not just saying that cause i own one

but it is the last 5.0....i personally don't care for 'verts myself, heavier etc....but check out stangnet.com...there are a couple of 'verts in the 12's with just heads/cam/intake....
but to your original ??? it depends on the usage of the car...if its just a daily driver or you plan on autoxing i'd say go with the csvt(although my stang is my dd)....if you are looking for a fun car to mod then i would say hands down get the stang,unless you can afford to do a turbo'd 3l....but then again that $$$ spent on the csvt would yeild better results with the stang...
as much as i loved my csvt(i'll probably pick another one up in a couple years for a dd)all that low and mid range torque of the stang always puts a smile on my face...and there are tons of suspension setups for the stang that can turn it into a good handler as well....its a tough choice,but i don't think you could go wrong with either..
