I should have been more specific - the S2 Exige came out in 2004. The S1 Exige came out in 2000 and was only available that year with 603 of them made. The Exige was not in production in 2001 to 2003
Hmm, I can only find info on the production run on Wikipedia and Seloc. Wikipedia states it ran to 2002. Not the best source, I know. Seloc says 2001. Both say 604 produced.
Wikipedia:
The first Exige used the round, less aggressive headlights of the first generation Elise, although the Elise was updated soon after the introduction of the Exige. The Series 1 was built until 2002, in 604 examples, and was not replaced until the Series 2 of 2004
