Something else to consider—how long were you planning to own this vehicle?
If you are planning to “drive it into the ground”, then worrying about someone seeing an accident in the history of the car (and it having a subsequently lower value) should not matter much.
Or, if you are planning to re-sell it, when were you planning to do that? Frankly when I’m looking at cars if I see an accident, followed by several years of normal ownership (and mileage), that won’t bother me much. My current car was in two accidents within the first 50K of it’s life… I bought it at 115K and it’s been decent ever since, no complaints.
Will it need a replacement battery? If so, that might actually be a good thing–you’re getting a replacement battery at 70K, it’s life is probably close to 1/2 over anyway…
