Q: Purchasing a used car that has been sitting for 7 years - worth considering?

Hi, I'm currently in the market for a used car (something reliable, daily commute etc). I came across a 2003 Honda Civic Hybrid with 43k miles with an asking price of $6900 from a used dealer. The CarFax looks decent (1 owner, no accidents). It was well maintained until 2009 but then looks like it was sitting for from Jan 2009 to June 2016. Leaving a gap in the report. In June, it passed safety inspections but failed the emissions inspection. July, it was serviced then a week later failed the emissions again. Then end of July - it passed the emission check. Is it worth considering this vehicle?

My car has 43000 miles.
My car has an automatic transmission.
