Car Appraisal in US Dollars, What would you appraise this car at in US Dollars Options

[tracks914]

Living where I live I only have one Auto Appraiser in town. ($350 for an appraisal) I know we don't do this for the money but I feel he might have under valued my car as he came in 50% less in value than my '72 1.7.
I would like to know what the worlds foremost authority on 914's think. Afterward I will tell all what he appraised my car at and hopefully I can take this to him and have him re assess the value.
I'm just finishing a restoration and want to get my car insured before I store it for winter. Here is what the car has.
1973 2.0
2.0 engine and drive line from an original 38,000 mile car.( I have known this car since I was a kid) Engine compression tested at 135 psi(x4), then torn down and re sealed and gasket ed and painted GT red. (Ok I made the GT red thing up) Same with transmission.
Monza 4 pipe exhaust

I'm sure there is much more that I am lissing but you get the point.
What do you think?
BTW the pictures in the garage don't do it justice.

The appraiser probably lowballed you as much as he thought he could get away with. The value of car should be determined like this:

What is the car? What are equivalent prices for cars that have had this type of work done to them?

The individual ones (leeway here):

How much cost in metal?
How much would an average body shop charge w/out parts to fix the metal?
How much would it cost for an average body shop to paint the car?

=Equals you basic cost of the car

Here in the US (general):

Paint: $5000
Metal: $800-1000
Shop to put metal in: $1000-$7000 or more depending on the (IMG:style_emoticons/default/bs.gif) factor and the (IMG:style_emoticons/default/icon8.gif) when they realize its a Porsche.

Rough Total: $10,800 (higher amount for the shop based in my local area)

The appraiser should of at least done enough homework to know how much it costs to paint and get metal restored.

The $10,800 should be the base at which he works off of.

How much for an engine rebuild?
How much for a transmission rebuild?
How much did it cost to bring the suspension back to equivalent standards for the car?
How much did it cost to bring the car back to standards concerning mechanical & safety issues?

That will probably be anywhere between $1,000-5,000 or more also depending on average shop prices.

With the custom interior work, you could easily lob off $1,500 on the selling price. It all depends on the buyer. Or it might add $1,500 in value.

A fair value for your car $13,500-14,000USD which would be 27,000-28,000 pounds in the UK.
