Nothing wrong w/ having an SR daily driver is there? It is a Nissan engine afterall, should last quite a bit.
Besides, why build a car then not drive it? If it was full-race, I'd understand but it's not.
In the end, you need a car that's built w/ reliabilty in mind. If you can't trust your car then you know what you have to do: make it reliable or part it out.
