1) They were NEVER V6, they're Inline 6 Cylinder (I6).
2) $5000 is WAY above book for a 16 year old car with nearly 150,000 on the odo, especially automatic. I personally doubt the 'excellent' condition based on it's age and location.
3) You didn't say, turbo or non-turbo. Non-turbo will go for less. (Turbo in EXCELLENT book for $3,700, Non Turbo's book at $3,000.)
