AP1 has no options for tire sizes… look into 17" rims to run a wider / better tire or go with an AP2.
Here is your s2000 buyers guide… lol
To me, theres only three things to actually take note between the model years. 2000 - 2001 has the plastic rear window… garbage. The center console is also wrapped in carpet. I am not 100% of the year where they switched the center console to leather, but it looks a lot better. Mines a 2003… leather center console.
2002+ has glass rear window… good way to go. Watch out for the soft tops… and the straps. Very common to have issues. Theres a lot of thoughts / ideas on s2ki to fix this prior to having issues. Top issue = all year s2000’s
Anything 2003 and older has 16" rims…
2004+ is ap2… 8grand redline, shorter gearing, facelift for exterior and interior, 17" rims, wider rims… better tire selection available.
2006+ has roll over hoop speakers, drive by wire throttle, vsa… and different rims than the 2004-2005.
Note: AP2 retainers are stronger than AP1… an issue with ap1 can lead to cracked retainers… overrev, etc. Also the s2000 is a great car to just get in and drive right from the factory… a lot of “mods”… suspension / springs… shit like that can actually hinder the performance of the s2000s handling. So watch out for that… even gc/koni combo is debateable…
