The centre bore is indeed an issue. The 350z has a a PCD of 5x114.3 and a centre bore of 67.1mm so any car with that centre bore or smaller, these wheels will fit. A range rover has a centre bore of 72.6 (forget that the PCD is wrong in this example) that means the 72.6 bore will not slot inside the 67.1 bore of the wheel. This means the wheels will not pull to the hub rendering it useless.
However. There are other cars you can retro fit these wheels too. These wheels are 5x114.3, pretty much all new age VAG cars are 5x112 with a centre bore of 57.1, so with some67.1 - 57.1 spigot rings and a set of variation bolts.

Then they can fit anything like a Mark 5 onwards Golf, Scirocco, A3, Passat, Transporter.
You then have the Mitsubishi Evo 4 upwards that is a direct bolt on, even the centrebore is good. 3000gt, Starion, Galant etc.
Oh and most Lexus's are 5x114.3.
With all that said, the only other issue (down to buyer) is to check the offsets are reasonable for their vehicle. That means making sure they don't stick too far out the arch, or to in the arch which means spacers will be required.
