There is one more side to donor builds.
Like others I started a scratch build with donor parts. Doing my own chassis work I had not to tape or protect any donor parts during the build. All parts have been for new ones replaced.
If I had kept and used the donor parts, the build would be about 30% of the amount what I have in it now.
It is really hard to tell if the donor or non donor route is more/less expensive.
My opinion: If someone is on such strict budget - maybe the Cobra is not their car to approach.
It is important to have a smile on your face while you are working on a project like that - right? (even middle in the wiring
)
