Tips for selling used cars over 10 years old... I've sold 3 of them

1. The one that gives you the lowest price is asking local dealers for quotes... You can basically consider them thieves. If they quote 1 million won, the car is originally worth at least 2 million won.
2. You should consider almost all bids on HeyDealer used car quotes to be fake. Even if you write everything down and take all the photos, they will come and use all sorts of excuses to depreciate the price. Don't be a sucker and sell it just because you feel bad that they traveled from far away while they are slashing the price. There are many scammers who will call you back a few hours later offering a higher price if you refuse to sell.
3. Honestly, if the car is over 10 years old and has bodywork/panel repairs, scrapping it is the right answer. HeyDealer also has a scrapping service, so just list it there for a quote from the start. You can consider that they almost never depreciate the price from the winning bid.
While the winning bid for used car sales is always higher than the scrap price, since on-site depreciation is almost guaranteed, I think for cars worth less than 1 million won, it's better to just click the scrap option to get more money and avoid wasting time.
This applies to old cars over 10 years old that are likely to incur repair costs.
