Ya know why it's quiet in here, because you haven't purchased 370 yet. Hehe, only kidding.
The only reason there's so many 350's on here is they've been out 8 years now, there's plenty about, including Jap imports to bolster numbers & the global economy was better. For the first 3-4 years could often drive for weeks if not months and not see another one (apart from meets obviously), but now will usually see one a week. Which still isn't much.
370's will ultimately be comparatively more rare because proportionately less have been sold. Should help the resale value, if you shift cars with any frequency.
Edit, I need Toby's job.
