Ana, you are in a predicament.
QIC is a highly reputable firm. I think they provide another vehicle FOC due to accident.
Yes, you will not get full 48K due to usage of 9 months that is expected, I cannot comment on the 38K. Any vehicle after it leaves the s/room looses 30 to 50% of its value, thereabouts.
Also, I think your loan provider is charging you the 5K as it is a full pay off during the 1st year. Per my knowledge, there is a fee if you fully pay off during the 1st year. They are loosing money.
I would recommend you visit your insurance and ask them to help you out for a higher value (which is doubtful) or they can claim from the other insurance firm.
Whether the lady that hit you accepts or not, by Qatar law, anyone ramming you from behind is at fault due to not maintaining enough distance.
Is she a Kebra driving school student/employee or the vehicle is a kebra driving school property. That could be a reason.
Just my thought, ff your insurance is giving you 38K+, you could go back to kia and ask for an earlier year new Picanto Line 2020 and pay the difference, which would be good as it will be an unused brand new vehicle, no monthly installments, 2021 vehicles will have arrived so they will want to get rid of 2020 vehicles. Just my thought.
All the best. I do not think I have any more useful information.
