If you need more pictures of the build I can send you a google drive link of 100's of pictures along the build.
I have tried to describe this vehicle as accurately and honestly as possible but please remember it is a used vehicle. As with any vehicle, (new or used) there may be issues that I have overlooked or am unaware of. If you are not familiar with purchasing used vehicles and or specialty vehicles or you have not purchased a vehicle using the Internet, please do your research, ask questions, make sure you are comfortable with me as a seller, the vehicle, and the process. Unless stated otherwise, I cannot verify actual miles and I am not offering a warranty so if you want one, let's discuss it and document it before the purchase is final. Otherwise there is no warranty expressed or implied thank you
