It all adds up. Or down. I still can not fathom how that car is 2550! Something isn't right. From the description though, there's certainly some weight in the car that could be lost (50) ....

In the end, it becomes a money deal. And often the money is better spent developing the driver. Once the driver is not the dullest part, then it gets spendy to find the last bits.

My car has gotten to it's weight the classic way. Every time something needed to be done, weight was a strong consideration. My fuel tank was rusting, so, I could replace it with new, ($$$) or put a cel in. In the end, the cel cost nearly what the stock tank cost, but there were weight savings with the cel. And so on.
