All 5AT owners, what's up with the 2004.5?
 

I have recently found out about the 2004.5. I have had my car for nearly a year, and I had no idea there are two 04 models. Supposedly 2004.5 models end with a 8XXXXX VIN. Is this true? What did they change in the car? I was told that the MM has less lag. Anything else?
