We're always on the hunt for affordable, reliable cars with a touch of luxury or performance — what if we told you there's a car with all of that wrapped up in one package? Enter: the Infiniti G37 Coupe. We know its reputation these days isn't always the most desirable, but there are plenty of clean examples left on the used market that are worth paying a premium for.Ignoring the units that have been thrashed by takeovers and/or straight-piped, the original G37 Coupe makes for a luxurious ride with plenty of power from its smooth, reliable engine. This article highlights one of the most underrated coupes on the used market. We'll discuss the G37 Coupe's powertrain, reliability, current used pricing, and more. Here's everything you need to know about the Infiniti G37 Coupe. The Grand Touring Coupe You Won't Expect InfinitiA grand touring car must hit a few marks, including styling, performance, comfort, and practicality — some might say the G37 Coupe hits a bullseye in every category. Firstly, the sleek styling still holds up today, and used examples in good condition still look great driving next to modern luxury coupes. Plus, it can also cover ground rather quickly, thanks to a potent naturally-aspirated V6 engine.No matter which trim you buy, all G37 coupes are comfortable, too; they feature bolstered, heated leather seats, a leather-wrapped steering wheel, well-balanced suspension, and more. Finally, they're practical. Despite being a coupe, it has two somewhat usable rear seats for small humans or more cargo. Plus, the rear seats fold down to expand the trunk, which is an area that's large enough to fit two golf bags full of clubs on its own (as demonstrated by a sticker on the inside of the trunk).The G37 Coupe followed a revolutionary model in the brand's lineup, the G35. Debuting for the 2008 model year, the G37 is still known today in enthusiast circles as one of the automaker's best models. It's reliable, powerful, looks great, and feels perfect for either a road trip or just as a comfortable, stylish daily driver. The Infiniti G37 Coupe Is Quick InfinitiThere may be a few trims to choose from, but they're all powered by a single fantastic engine. Its 3.7-liter naturally-aspirated V6, part of the VQ engine family, makes 330 horsepower in the Base, Journey, and Sport trims, and 348 hp in a special variant called the IPL, which we'll get to next. The 2008 model year only came with a five-speed automatic transmission. However, soon after the coupe came out, buyers could choose between a seven-speed automatic and a six-speed manual. Those equipped with automatic transmissions are quickest, with a roughly 5.4-second 0-60 mph sprint, and most top out at 155 mph (although some are limited to slightly lower speeds). For More Power, Try the G37 Coupe IPL InfinitiThe IPL, or Infiniti Performance Line, variant of the G37 coupe was short-lived, and the badge unfortunately never returned on any other Infiniti models. IPL was intended to take BMW's M division head-on, but the result was fairly underwhelming. Infiniti gave this variant unique wheels, bumpers, side skirts, a spoiler, and other cosmetic upgrades, but its performance upgrades simply didn't match the hype. That said, it's still just as good of a car as any other G37 model. It had some more horsepower, but its performance was never pushed to the point of BMW's M cars. Plenty of Power, Sourced Reliably InfinitiThe best part about the Infiniti G37 is that its powertrain is virtually bulletproof. Nissan's VQ37VHR can reliably handle its own power, and it's strong enough to take as many bolt-on mods as you can throw at it. That said, keeping it stock is the best way to increase its longevity. There are no outstanding complaints or significant problems with its engine or transmissions, and other customer complaints are generally kept to a minimum. Here are the best and worst model years for reliability. The Most Reliable G37 Coupe Model Year InfinitiIt's pretty common for the last couple model years of any vehicle to have fewer issues than earlier models, since manufacturers tend to work out any problems throughout the model's life. Therefore, it only makes sense that the 2013 G37 is the best. Even though it has the fewest complaints, it's not perfect. The 2013 G37 still has issues with the sunroof drain (as does essentially every G37 model), and there are still numerous complaints about the passenger airbag light turning on, which is allegedly caused by a bad sensor in the seat. Keeping It Fair: the Least-Reliable G37 Coupe InfinitiWhile it's true that earlier model years can have more problems than others, the earliest G37 years are still strong, dependable cars. However, if we're basing our findings on the number and severity of customer complaints online, MY2009 should be avoided. Some of the highlights include water dripping into the cabin, which is usually caused by a blocked sunroof drain, a small handful of owners report having the car stall or go into limp mode while driving, and there are tons of reports of the airbag warning light turning due to a bad sensor in the passenger seat. Since the number of people complaining about stalling is so low, though, it would be wrong to call it a "common" problem, and it could possibly be down to just poor maintenance at this age. Used G37 Coupe Prices Today InfinitiThe chart above provides a snapshot of where late G37 Coupe values currently are. This does not necessarily represent every G37 you'll come across — it's important to realize that used car prices vary greatly for many reasons. Prices for each model year could be different depending on trim level, mileage, number of owners, overall cosmetic condition, overall mechanical condition, its record of accidents (or lack thereof), any maintenance that may be required, and more. Like all used cars, G37 prices vary greatly depending on their previous owners. Examples with fewer previous owners and good maintenance records will be worth more in the long run.Some cars may hold value better than others. On that note, there may be some 2008 model year examples well-worth over $10,000, just as much as there might be some final model year (2013) examples worth around $5,000. At the end of the day, we're confident that no matter where in the country you are, you should be able to find some in decent condition from one model year or another for under $10k, and they should be plenty reliable with minimal maintenance. When searching for a used G37, it's more important than ever to take a close look at both the car itself, and the owner. Robust And Plentiful Aftermarket Parts Availability Sean McManusWhile the G37 Coupe is a near-perfect car on its own, another great appeal to this platform is its aftermarket accessibility. Most of us have probably seen — or heard from a mile away — the obscene, slammed, otherwise beat-up G37 models (usually sedans, since they're cheaper). However, like the example pictured above, it doesn't have to be that way. The photo above is a recent shot of this writer's 2008 G37 Journey Coupe. To maintain a mix of class and sportiness, I kept high-impact cosmetic mods to a minimum.That said, current owners have a world of customization at their fingertips. For example, my G37 has aftermarket headlights, taillights, wheels, a spoiler, a catback exhaust, a cold-air intake, a strut bar, carbon fenders, carbon mesh grille, and drilled/slotted brake rotors. It doesn't have to stop there, though; other possibilities include coilover or air suspension, some people replace the factory infotainment system with a larger screen, starlight headliners that look like they're from a Rolls-Royce, and more. In Summary, There's A Lot To Like Sean McManusDespite what prejudices some of you may have about the Infiniti G37, its coupe variant still makes for a great GT car in 2026. Today, buyers can find examples in great condition for $10k-$15k, and average condition for under $10,000 with ease. Pricing aside, this coupe looks great, its quick enough for daily driving with some canyon roads or track days sprinkled in, and its interior is plenty comfortable for two people. Large trunk space makes for a practical weekend getaway car, too, should you need to pack luggage. It's everything enthusiasts ask for these days, with an optional manual transmission, a robust, powerful engine, and more.
