I have a 1980 911 SC sunroof coupe on which the insurance is coming up for renewal. For the last 4-5 years I have had it insured for an agreed value of $23,000. However, about 2 years ago, I rebuilt the engine making it a 3.3SS. I spent about $11-12K on the rebuild using only the original block, crank, oil pump and flywheel with everything else new including an Electromotive XDi twin plug system. Under the circumstances, I need to increase the agreed value for the car and am considering pushing the value up to $35K. The question is, do you think that is a fair value? The car has had a bare metal paint job and new interior along with most everything else having been replaced or rebuilt.
