If I recall, the only E21's that Toyota replaced were the original '99's due to a claim that the original mold had a slight warp, and there had been claims of chine lock. Rather than dispute it, Toyota replaced every E21 that had been delivered to that point--pretty amazing.
Pete K. knows the details on this(I think either he, or one of the dealers on Lake Lanier, told me about it when I was looking to buy one that had been replaced by Toyota, but never driven by the owner due to a divorce).
If you have a 2001, you should be OK.
