My brother bought his 99 EX for around 15.5. All power options, no spoiler.
Price range can vary depending on the area you live in. My friend sold his 99 EX (EXACT same car as mine) with 17" rims, intake, header, apexi ws2 catback, and like 105k miles for...4500? If it's a complete rusted shitbox used as a beater, it shouldn't be worth more than a few grand.
