First time I ever built something like this. Kit was pretty much as advertised, very complete, manual fairly good but
www.ffcobra.com is your best buddy during the build and for research.
Few people use the donor gauge set and all most everyone spends a bunch of money on better trim pieces, chrome plating upgrades and tires and wheels.
The finished product is great, but as with anything one builds, the result depends on the care taken by the builder. Almost no one does the body prep and paint themselves. I spend $3,000 on this and it was well worth the money.
I am totally satisfied with my Factory Five and have now driven it about $13,000 miles this year since completion. My total cost was $26,000, this was a fairly basic build with a top, tonneau cover, bumpers and lots of trim upgrades from various vendors.
