Not particularly rare in today's used-car market; Infiniti produced the G37 lineup from 2007 to 2013 across sedan, coupe and convertible body styles. In general, sedans are the most common, while coupes and convertibles are scarcer, and manual transmissions are relatively rare.
What the G37 offered
The G37 carried a 3.7-liter V6 engine and produced roughly 330 horsepower, with most examples sold through automatic transmissions. The line spanned several body styles—sedan, coupe, and convertible—and production wound down around 2013 as Infiniti shifted its strategy to the Q50 lineup in 2014. This means current buyers are seeking late-model used cars rather than new vehicles.
Rarity by body style
Because more G37 sedans were produced than coupes or convertibles, today you’ll see more sedans available on the market. Coupes and especially convertibles are noticeably rarer and can carry a modest price premium if they are well cared for and have lower mileage.
Transmission availability
Automatic transmissions were by far the most common choice for G37 buyers. Manual transmissions exist but are comparatively uncommon; if a manual is important to you, you’ll need to search carefully and may have to widen the model-year range or trim preferences.
The current used-market picture
In the present market, listings vary widely based on mileage, condition, options, and maintenance history. As aging luxury vehicles, G37s often require attention to suspension components, brakes, and routine maintenance, which can influence the total cost of ownership beyond the listing price.
Summary
Overall, Infiniti G37s are not broadly rare. They remain fairly available in the used market, especially the sedan variant. If your idea of “rare” means a low-mileage, manual coupe or convertible, those examples exist but are harder to find and may command a premium. For most buyers, the G37 represents a readily accessible option within the late-2000s to early-2010s luxury-sport segment.
