It still could be a late model if it's had a hit and the panels where replaced with early stuff.What do the tail lights look like,any signs of it having 3 on the tree,steering wheel design etc.When all else fails check the factory compliance plate,drivers side inner guard between the fuse box and fire wall,the chassis number is also stamped into this area and should correspond with the plate.But at the end of the day who cares as these beasts are getting as rare as rocking horse manure in any sort of half decent condition
