its not always 20% my formula i wrecked i gotaround 7000 for it and i bought it back for 440 bucs… they try to figure what it woudl take at the auction with that amount of damage and then allow you first dealings. and if you insure it for 20 g’s and it gets wrecked back you prob would have to buy it back for a portion of that 20 g’s but maybe just what it would take at auction.
