07 honda civic ex coupe accident estimate 8k damage?

Last Tuesday I go into an accident w/ a tractor trailer on a busy highway, I got rear ended and then pushed into the car in front of me. I finally got the estimate today and it’s $8k w/ brand new honda parts (no refurb. or recond.). My father has been a mechanic for over 18 years. He is saying if my small car has $8k worth of damage then the car will eventually have further complications. Basically once the frame is damaged there will be consequences even after the car is repaired. He is saying that the car will eventually start shaking and be near impossible to sell. He told me that I should fight the opposing insurance co. to have my car replaced at total cost. Which according to blue book is about 15,500k I have 11k on my loan left. Should I fix the car or should I go with what my father is telling me. The auto body place told me that its due to the original parts. my radiator ac hood trunk bumpers fenders lights battery grill license plate things are damaged so far…

In general, if you don’t know anything about cars, i would listen to the advice of your dad. I however, would fix the car since 8K damage for an 07 isn’t major as far as i am concerned. I have built cars for over 40 years including the frames before the unibodies and the unibodies can be pulled back to the right dimensions (and that’s more than an 8K hit) that would be a totaled car. What often happens in the front & rear hits in the more minor hits is that the car may need a little pull on the ends that are hit to straighten out the areas around the (bumper) attatchments. If your engine cradle is bent or the strut towers then the car is usually totaled, so yours is probably not. I assume it needs both ends of misc lights, f fenders, hood rad, ac, core support or straighened and a little pulling on a frame machine.
Any car, esp unibody that isn’t repaired right if diamond hit (tweaked) will not be able to be aligned without going outside the limits and will eventually wear tires, bushings, tie rod ends, steering rank and the like and will shake.
So if you have a professional fix it right, it will be OK. Most body shops dont do as good a job as they should (time=money) so if you fix it get a real pro.

I frequently get cars from IAA insurance auto salvage & fix them correctly. Some are bought for parts.
