That's low mileage, big plus, however the automatic is a minus, as most enthusiasts are looking for manual transmissions. I am in Canada, but IMO if the car is mechanically well maintained and as clean as you claim I would put it between $10 000 and $12 500. Maybe a little less for an acquaintance as you say. More then that and there are a lot of nice cars available. For reference, I paid $15000 CDN for a mint low mileage 2004 Cic with sport, cold + nav. 50000 miles, never winter driven, good maintenance history. I feel I paid a premium value, not a deal by any means, but the car was uber clean, so that's why I decided to pay a premium.
Good luck and welcome to the community!
