I'm planning to buy a 2008 honda civic that has been written off but repaired already should i buy it?

Price is 8500$ and done only 90k's the damaged is on the rear side.

You can get a clean title one for that amount, keep looking. A salvaged car should be worth less than that.

I searched for 30 seconds and found over a dozen 2008 Civics with less mileage, clean titles, and were priced over $1000 less that the salvage car that you want to buy. Should be way less.
