Is the Nissan 350Z a good investment?

The thesis

RWD, 3.5L V6 (280–313hp), manual-only focus, and affordable. The 350Z sits in the shadow of Skyline/GT-R JDM hype, so it hasn't seen the same run. Clean UK RHD manuals sit £10k–16k. It's a usable, reliable GT with strong bones. Not as revered as an S2000, but that's exactly why it's early-cycle. Values stable to rising gently.
