Welcome to the OC
At this age, many Zeds have had a new exhaust due to corrosion at the flange just behind the backbox that joins it to the midpipe.
Saying that, I've cleaned there regularly over the past 14 years on my zed and the original exhaust is still fine!
If it is falling apart here you could use it to haggle a little off.
It's no biggy as you can either get a stainless system from Scorpion, Cobra, Miltek, invidia etc or just pay a shop to weld a piece of pipe in to replace the flange.
Mine's just gone over 60k and needed new banana arms as I was getting a knocking noise from front wheels going over bumps at slow speed.
Can't remember how much these were but better searching for Mooge aftermarket ones than Nissan OEM as they are about half the price.
Rear boot may not stay up as the struts age......so careful when checking the boot in case it falls on your neck like a guillotine!
