Yes, definitely.
Any Z under $20,000 right now would be a harmed one. There are many on the market selling as low as $17,000 these are the same 350Z’s that have been in collision on the track or street, there are just too many of them with bumper damage and paint overs, that I have seen at used dealers for under 20k, I started noticing the difference of quality after $25k for 2003 model.
As for a Nissan under 20k, I’d buy that skyline debuted in the magazine, that car is flaming.
Unless you are really rich, spend that kind of money on a daily driver, like VIP style cars, and maybe later on 5K on a working project.
I’m looking to buy an S-class, turn it into VIP with just rims, and that’s it, and later look for a Nissan project to play with.
