No its absolutely fine Dom as long as the other guy has admitted fault ? Ie its a third party claim ?
It actually puts you in a really strong position
First thing to know is in the case of a third party fault claim you have the right to to INSIST your car is repaired regardless of if repair costs are more then the vehicles value UNLESS the vehicle has been rendered structurally unsafe ,, im guessing it hasnt
So you can just insist on it getting repaired
You should also have a like for vehicle ,, so a modern subaru type performance vehicle to drive till its all resolved if yours is in for estimates etc
If for example they had to order a bumper from japan to fix your car after you insist it be fixed it could take a long while for parts to arrive so best to sort out a suitable car right at the start ,, my 2002 lr got fixed last year and it took about 5 weeks ,, in that time i had a brand new m sport x5 to slum about in
From the sound of it the insurance would probably be ready to negotiate with you about writing your car off as it might be easier for them but as it wasnt your fault and if the other driver has clearly accepted fault to the insurance companies not just to you then if it was me i would be looking for a decent cheque for value of sti and the car back for say ten to 20 percent of value ,,, ie you get paid and keep the car so you can repair it yourself albeit it will be on the vic register as a write off due to uneconomical to repair
Then just document the damage and fix with fotos and should still retain some value for resale later
The crucial thing is ,, has the other driver notified his or your insurance company that he is at fault ?
