The Beretta wouldn't be my first choice, but I know this guy is top notch on maintaining his vehicles and they are all garage kept, sythetically lubricated, etc..

I saw a 10% gain, 1.5 mpg with it. My fuel expenses are around $250 per month, so maybe I was saving $25/month. I care more about how quiet it is now than before, however. I never thought hearing tire noise was such a sweet sound until I could finally hear it. I shouldn't have gone that route. Chalk it up...

Now I'll be cruising in style with a red Beretta with red wheels. $$
