Does this refer only to trim and variant years, or to the model and engine family years as well?
At any rate, I am thinking of creating a cheaper version of my Shadowclaw with a trim year of 1995 - but if the rules state that the model year must also be between 1995 and 2000 inclusive, then I’ll clone the entire car model, set the model year to 1995 and then adapt it for this rule set with a suitable engine, probably an I4 or I6.
