my guess with that date it's an '04[?]

 

Check you VIN # The 10th digit from the left is the year. It wiil be a 3 or 4

 

Not to correct Frosty but, my experience is that the 10th digit is the year. I know for positive that is how it works on vehicles from 2000 & up & it has always worked for other toys up to this point.

 

That is what I ment 10th digit . Had something else on my mind at the same time. I guess. I know the 10th is correct on current models in stock.

 

Stop bickering. Any vehicle that has a 17 digit VIN is model year identifiable by the 10th digit since 1980 as follows
The letters I, O, Q, U, and Z are not used because they can be easily confused with a number or another letter.

A – 1980

B – 1981

D – 1983

E – 1984
