Repairs often run over estimates when you get into the damage.
Hence the 70% value and they still have the car for sale for spares and scrap.
Hello
They look up the "Book Value" of your car as was before the accident and if the estimates for the repairs are for more than that it is Written Off. However they will probably ask fora quote from a dealership type garage so it will be high. Depending on the damage you can opt to keep it and get it repaired at a cheaper corner garage

Do You Know Why Car Insurance Costs So Much?
Car insurers will not only judge you based on your record, but on the records of other people similar to you. More info in the source link!

Based on the total damage and the cost to repair vs replace
If the cost of the repairs exceed the value of the vehicle less the scrap value of the vehicle, they total the vehicle to save themselves some money.
If the damage is worth more than the retail value of the car, it is considered totaled.
#1. Age of car.
#2. Money required to fix the car as cheaply as possible.
Generally if the frame is bent they will total the vehicle.
