It would be a good idea if the Accord wasn't first sold here in 1976.
The 10th anniversery addition was to celebrate the 10th anniversary of the Marysville, Ohio plant opening. Don't expect a 20th anniversary, as Japanese manufacturers building cars in the US isn't as big of a deal now as it was 20 years ago or even 10 years ago.
Honda doesn't really "do" anniversary additions :dunno:
