What year is my Previa?

Thanks that was really informative. I'm selling a Toyota Previa for a friend tomorrow to a guy coming from out of state. My friend wants 500 and I have it listed for 625 firm. As you may know folks like deals... It has 276000 miles on it, good tags, moderately dented body, no frame damage, fair tires and a side rear window with missing locking clips, and check engine light on. It runs and drives with no leaks or obvious signs engine trouble. We have optional snow tires brand new for 100$. Which is a great deal so I'm telling the buyer that there 200$ and can be sold with the van.

Thanks again
