Somebody right now is on Craigslist staring at a 2009 G37 sedan with 94K miles, clean title, $9,500 — and they're about to pull the trigger thinking they just found a luxury sport sedan for Civic money. I get it. The VQ37VHR is one of Nissan's best motors ever made. 330hp, rev-happy, sounds incredible through a decent exhaust. The chassis is basically a slightly softer 370Z. On paper, it's the move. But there's a reason clean G37 sedans from 2008-2011 are priced where they are, and it's not because the market forgot about them. The oil gallery gasket issue on those early VQ37s is the kind of problem that doesn't show up on a test drive. It doesn't throw a code until it's already too late. The gasket degrades, oil pressure drops, and by the time you notice the motor is starving itself. That's not a $400 gasket job either — you're pulling the motor or dropping the subframe depending on who's doing the work, and if it's already caused bearing damage, you're looking at a long block swap...
