I highly doubt there was a Special Service (police) package in 93... but i could be wrong. check the RPO tag for code B4C. they made them in 91-92 but i dont think they came back until the LS1 4th gens.
as for the price, that is a lot of miles for a car that needs atleast another grand in work, however if u do the fuel pump yourself itll be about 100 bucks, and im sure itll need other stuff too. if i were u, id save a few more paychecks and get an ls1 car
edit!!!!! i stand corrected! it was the rarest year with only 135 made... buy it and keep her stock
