Would be a crying shame if you had to pass the car off. I lost my first car, which was a unique KE70, and it broke my heart. Felt like I was breaking up with a first love. Yours looks three times better than what mine was, so I can only imagine what you'd be feeling if you had to let it go.
Keep at it, though. If it's such a well-built car, it surely can't be knocked back for much in the respects engineering quality. Meaning you may be required to engineer the car at worst. Chin up. you might even pass with flying colours! :y:
