[auto parts] - To short year (i.e. '02 or full year 2002) Does it matter?

For selling auto parts on Google Base Product Search, would you recommend, in the title to write:

a) 02 2002 Toyota ... whatever
b) 2002 Toyota .....


Is Google smart enough to know 02 is 2002? Is this irrelevant?

I looked at high ranking feeds and they are split 40/60%. 40% do option b, and 60% do both years.

I am confused by this does anyone suspect or know anything about this?

thanks for any and all advice,
