1973 OPEL GT - GORGEOUS CAR - OWNER RESTORATION - OVER $15,000 INVESTED!

PLEASE READ ENTIRE POSTING BEFORE BIDDING
It is with much regret that I am selling my 1973 Opel GT. I purchased from the owner of 34 years; it was a daily driver. The car didn't look great but the body was straight, o rust and the car has always been in California.I have owned this car for 8 years and a minute after I purchased I began my restoration. I have well over $15,000 in receipts and 100's of hours of my time.
I am selling the car for two reasons; one is that I had surgery on my neck and can no longer get inside lowered cars. The other is that the rebuilt engine bogs down at high RPM and I don't know why. I brought to a Carburetor specialist who calibrated the 38/38 Weber carburetor perfectly, t idles, evs, tarts right up and will drive at speed. If you put your foot into it it will bog but get to RPM. It could be the fuel pump, t could be that the car just needs to be driven as I have put no more than 5 miles on the car since I have owned it.
That said, lmost everything has been replaced on this car; It will be difficult to list everything but I will try.

I am sure there is more. Opel GT Source has provided the majority of parts; the Engine/Trans was from Opels Unlimited. This is a gorgeous car with a great amount of work and money into it and I should not be selling with the handicap of the issue with the engine. This car is easily worth $15,000-$18,000. I just can't work on the car any longer and cannot drive to see if it just needs to run through a new tank of Premium to work out the kinks.
I have boxes and boxes of extra parts; new and used; all go with the car. Car is registered in California with a clear title in my name. Car is available to see and drive. While I am saying I replaced most everything on this car I am not saying it is perfect. This car was not done professionally; it was done in my garage by me in my spare time. What was done professionally was the paint job and installation of the engine and transmission. Car looks amazing because I am a bit of a perfectionist but just saying; still a 43 year old car.
I have original owners manual (see pictures) for car that was purchased at Seaside Buick. I have repair manuals as well. Car is being offered AS-IS and I am explaining to the best of my abilities.
