Sometimes the trim will be indicated by the VIN, not all the time though.
Given that snippet of the VIN: 4T1BG12
4 - Country of Origin: USA
T - Manufacturer: Toyota
1 - Vehicle Type: Passenger Car
B - Body: 4 door Sedan
G - Engine: 2.2L 4 cylinder (5S-FE)
1 - Series Code: (tied with postion #4, )
2 - Restraint: Manual Belts w/Driver\'s Side Airbag
The next 4 positions, I guess, based on the most common ones out there.
X - Model / Platform (should be a \"K\" for Camry)
X - Check Digit (could be anything, used to verify legit VIN)
X - Model Year: (should be a 6 for 2006)
X - Manufacturing Plant: (Likely U - for the Kentucky plant, other valid entries are M,R,S,W,X,Z for other USA plants)
XXXXXX - Positions #12-#17 are for the unique serial number for this car.

Don\'t take it as absolute truth, only way to know for sure is to pull the original worksheet for the car (i.e., Window Sticker and associated build sheet that they sometimes stuff into the car).
