I've seen a lot of Z's in my day. Chances are that the rot in the floors isn't the only cancer on the car. A few holes in the pan here and there on a 280z is expected. If it weren't for the seat mount your ass would be on the pavement. And sinse I can see the rails from the pics, they can't be very structurally sound. My guess is that this was a northern car that saw slot of salt. It takes a lot of snooping and prodding to find hidden rust and I suggest any buyer be aware that firewalls are known to being kicked through. My first Z had this problem. It became a parts car very soon after my friend stretched his legs and(crush) no more lower right firewall. $1000 is a more acurate price given what I've seen. If the motor is cherry than maby $1500. Not trying to bust your bubble but the one mistake Z shoppers make is not checking for rust everywhere. Once a box section of the unibody is rotted out it's going to cost a lot of $ or your driving a verry unsafe classic Z. Just my 2cents but after buying what I thought was a solid car turned in to an expensive parts car. GLWS
