If your car is considered a total loss, insurance company will pay "market value". For a low volume vehicle like the VX they will probably rely on NADA/KBB value. You may want to start collecting classified ads for VX's for same year/mileage in case they try to low-ball you on the offer, (especially as it is the other guy's insurance), so you have proof of what VX's are selling for.
If you want to keep the salvage, the insurance company will just deduct the amount they would get from salvage company from what they are paying you for the total, however it would depend on the laws of your state. I think some states do not allow you to retain ownership if the vehicle is declared a total loss....
