Sorry about that! I didn't pay close enough attention to the question...
Look in the driver's door jamb at the build plate: there will be the month & year. Lower down you'll have 6 numbers, first 2 are the month, next 2 are day & the last 2 are the hour in 24 hr time.
Or an alternative to find just the year, look at the 10th digit of the VIN - the number just before the 'X'...
