earliest VINs I have recorded are:
"B" - MI - JH23H0B1158xx - SPD 90?
"E" - LA - JH23H0E1096xx - SPD A03

Effective immediately, F70x14-inch RWL tires (T87) are standard with the 340 Performance Package. The E60x15-inch tires (U82) will be optional at extra cost. The Collapsible Spare (W34) and Rallye Wheels will no longer be required with the 340 Package. A Rear Spoiler in Dull Black (J81) will be available in early November. Effective immediately, Performance Axle Packages A31 and A36 are available with the 340 Package.




Effective immeadiately - DID THEY CUT THE PRICE by ~ $50? or add other features to the "package"?
