My gf is getting her Granny's 2002 jetta wagon with amenities, sunroof, etc. Looks new , works well, probably needs a tuneup bc it hasn't been ridden in a while. Anyone know what it's worth? $$?

Bb is around $5k, but I think it's worth more bc it has very little wear and tear. Only 50,000 granny miles! Any thoughts?
