So I just bought an '06 9-3 Aero and I was looking through the owners manual when I came across something weird. The owners manual has a section where it decodes the Vin #; telling what each digit means. The fifth digit is supposed to be an F to decode the car as an Aero. So a typical Aero's first 5 digits would be YS3FF. But mine is YS3FH. The manual doesn't make any mention of an "H" Everything else checks out from the Vin; 2006, 2.8 V6, 6-speed auto. I know it was built in August of 2005 so it was a very early 06 model. Any idea what the H means?
