$5K I would say no..... there are so many things that will cost yuo $20 here and there it will add up. Also you will have about a $1500 in paint supplies even if you are doing it yourself.
Not sure what all you are doing or how far you want to take it but I have everything but glass and I am $35k plus my time.
If I do anything with paint such as flames or graphics that I cant or dont want to do myself I will have another $5k in it.
Good luck with your build but I am finding out that this is not as cheap as I was hoping for.
But then again we might want different results
