no, there substantial upgrades between the 98 to the 99/00s, its wortth the extra money to get a 99/00, really if your gonna get a classic get a 99 or 00.

98s only have 2 pot front brakes 99/00 have 4, the injectors are bigger, 380cc in the 98 - 440cc in the 99/00), cosmetic upgrade include the bigger rear wing and more aggressive style front bar, momo steering wheel replaces the nardi wheel and a passenger airbag is fitted in the dash rather then a compartment on the 98's. thats about all i can remember between them off the top of my head atm. betweenthe 99 and 00s (00's more conservative i think?) theres not much different, different style of rims and a different ecu tune i think are the only main differences.
