Bro, zaruri nai hai. May b jiss denter / painter ney aapko ye faults btayeye hain, wo khudd b zyada expert na ho? Sometimes, potential buyers jinn mechanics, denters / painters ko ley k aata hain, unki aur buyers ki setting b hoti hai, and wo jaan bujh k wo wo nuks b nikalnay ki koshish kartay hain, jo shayed exist b na kartay hoon!
I would suggest to take second opinion, and may be, from pakwheels car inspection service. Mainay 2 baar ye service use ki hai, and I am highly satisfied. They have specialized tools / guages for monitoring dents / paints. Aapko apni car ki true picture b samnay aa jye gee, buyers ka trust b build ho ga, and may be, you are able to get excellent price for your car.
And Yes, you are right. Serious log kamm hotay hain, but chaskay aur mazay lainay walay zyada. Na laina / Na daina, buss guppshupp lgayeye aur baat khatam. Disheart matt hoye ga, and Don't worry! If you are willing to sell your car, it will definitely get sold. Just take some time and let potential serious buyers approach you.
