@sportscarguy3. With respect, I strongly disagree with you. I agree with @jwestracing and he is probably a little low. I think you are confusing what it costs to build a car like this vs what the market valued it at yesterday. Perhaps you are not familiar with the parts and labor costs to build such a car in today's economy. This is a nice build and a lot of effort went into body gaps, underside finishes as well as the frunk and engine bay and bodywork and paint work. Backdating a G body to a long hood is not as simple as it looks. You can easily spend close to 100 hours just to get the hood, front fenders, flares, bumper, turn signals, headlights, horn grilles and weatherstrip pieces all to fit as well as this car. Here is a simple breakdown of costs.
1- Rust free donor G body 911 --- $50K
2- Body parts for longhood conversion --- $8-10k
3- 3.2 Engine and aluminum 915 tranny with minimum "freshen up" --- $30-40k
4-Bodyshop and paint supplies -- easily $5-7K
5- Wheels and tires --$6k
6- Interior with new seats-- $5-10k
7- Electrical systems gauges etc.-- $3k
8- Suspension and brake systems -- $4k
So, just the parts and supplies alone will be at least $130k.
Labor ---- Porsche shops capable of this build quality will be anywhere from $150-$250/hour (yes, I checked current rates). Lets use $200/hour as a middle figure. To be at $250k total build costs that leaves ---- $250k - 130k or $120k for labor. At $200/hr that is 600 hours. I can assure you that this build was way greater than 600 hours.
Not to mention the time the owner (presumably) spent coordinating the build, shuffling the car around to various shops, finding parts and tying up his capital for a few years. So, when you stated that this build could be done for " much much less than what jwestracing was suggesting" I think you are not seeing the whole picture here. Just my 2 cents.
