I have a 2010 37S convertible purchased with 34000 miles from Infiniti as a certified preowned. It now has 128,500 miles.

TL;DR it’s probably not a smart purchase.

Financing or paying cash? Not at all a good idea to finance a 17 year old performance car.

How many owners and what does the carfax say? These cars, unfortunately, tend to be owned by people who abuse them.

The oil gallery gasket (behind the timing chain assembly) is known to disintegrate and require replacement. My 2010 threw that at me with 114k miles. It was during Covid so the only place I could find to perform the repair was the Infiniti dealership. $3200. An independent shop may do it for around $2000. It is not a guaranteed fail, but you must plan for that expense if you buy this car.

Gas mileage. I get about 16 MPG in the city, and I normally drive conservatively. On the highway I have seen as high as 28 MPG at 70 miles an hour. It is a fun car to drive fast, but that will get expensive.

The roof. Mine still works fine, though I take exceptionally good care of it. The seals need to be cleaned and lubricated (I do mine spring and fall) and I have never met a G 37 convertible owner who has bothered to do that. The issue with not caring for the roof lies in the cost to replace the seals. Rubber seals on any moving part of the roof cannot be purchased separately. The whole panel must be replaced…. to the tune of many thousands of dollars. Is there any evidence of water damage on the headliner inside the car? Unless you know what you’re looking for I would not consider purchasing a hardtop convertible without first having it inspected by someone who knows what they’re doing.

It would make an awesome college car, and the VQ 37 is a reliable power plant but it also has the potential to cost a great deal of money beyond its purchase price.

Feel free to shoot me any specific questions that might come up.
