I just rolled in from an 1100 mile round trip this weekend. Up and down I-5 from northern San Diego to the mountains past Sacramento in 95 degree temps all the way. I kept the top up on the freeway and the noise was maybe a little more than a closed car, but I like the windows down, so it didn't bother me at all.
Oh, but when I got there, I dropped the top. How can you beat that? I bought the car because I like ragtops, and I sure like the Mustang's power. Mine's an auto--ever driven in Southern California traffic? My trip included two sojurns through LA, one on Friday afternoon. Need I say more?
My car is stock for now. I'll add a Bassani exhaust, an Eibach pro-kit, some beter looking wheels, and clear Cobra headlights and I'll have a great ride. No other performance mods, unless I go with a Kenne Bell SC. It's fast enough now for the street, which is where I drive.
I bought the car because I love it, not to turn heads, and I'm mature (old?) enough not to be concerned with that. But you would have been amazed at how women of all ages turned their heads, smiled, and waved at me as I cruised the main drag.
Buy the Vert.
