Why shouldn't I purchase this car?

I just saw a 1996 Honda Civic for $2,996.00 with 89,000 mi on it. I'm planning to purchase it from a reputable dealership, I did background check on the car and it had one minor accident from someone hitting the left rear bumper. No odometer changes, no other accode ts, no issues in any other place. I looked at the car and it is in very good condition. I drove it doesn't have any issues thus far. I also plan on getting it a thorough inspection tocmake sure all is in good condition by my mechanic.

Aside from my mechanic's inspection so far everything checks out with it. Is there any reason people aren't jumpinf at the chance to buy up these low mileage cars? Is it because they are old and people just want to keep up with Joneses? I mean it's a clean car with low miles, 31 mpg. Can't imagine why someone wouldn't purchase a car like this aside from the aforementioned.

I'm saving up for my house and so I don't want to add a car payment to my debt, in fact I would like to stay away from debt as much as possible. I just need something for work and possibly just drive to my friends' houses.

I looked at the carfax and there an accident in 2010 and the car needed to be towed. I talked to the owner and he didn't know about it but from what he told me he said he replaced almost everything in the engine.
