kbb.com said a 2000 s2k with 60k on it in 'excellent condition' would go for around 16k. thats a private party value. i'd imagine most s2000s have a lot less mileage on them being as most are not daily drivers.
That's nowhere near the value in cali, maybe in MD that's what Kelly says it's worth but here you can't touch a nice one for over 25k. I see dealer selling them for over 30k all the time.
