Well as I said in another tread so can I buy a 8000 USD car and have the same expences on sheetmetal that I will have on this one.

Sure it will not look so bad, but after changing the lower quarters, the lower fenders, the trunk floor and patched up the floor the cost will be the same.

I think it is easier to change a whole panel than to cut and patch, the result will be better and you will for sure not use any more time on it.
