I'm planning to sell my car soon and someone suggested I should get it checked on a dyno first just to have some kind of performance proof if a buyer asks, but I'm honestly not sure if that actually adds any real value or if it's just something car enthusiasts care about, I did a bit of digging online and ended up on www.dynostarworkshop.com (https://dynostarworkshop.com/) while trying to understand how these tests are usually presented to customers, but I still can't tell if showing dyno results really helps in negotiations or if most buyers just ignore it completely and focus on mileage and condition, has anyone here actually used dyno results when selling and noticed any difference in how buyers react?
