I was astounded when I bought my rig in 2015, almost gave up and thought I was chasing a dream. Everything was a rollback. I had some deal that Carfax doesn’t offer anymore (unlimited) must have run a dozen or more till I found my black sheep: out of state reg., faded paint, guy was selling it for his buddy who had cancer... nobody bit on it but it checked out at 163k, full maintenance records from 2nd owner of 8 years (who was a realtor in Idaho btw). The interior was immaculate. Then I poured 2k into it to get it up to speed.
You are no doubt rolling the dice with any used car. Dont forget to account for the sweat equity you’ve invested already. No reason to abandon her if she’s solid, be patient, garage gems take a while to find any way.
