I have a bit of advice for Infiniti salespeople.

The next time somebody saunters into the dealership to look at the Infiniti G37 coupe, ask them to be seated in those comfy leather seats, hit the starter button and let them listen to the incredible sound coming from those dual exhausts -- tones somewhere between a metallic moan and the cry of a banshee. All resistance will melt. They won't even need a test drive. Where are the papers to sign?

As it turns out, Infiniti focused a lot of attention on that exhaust sound.

"The exhaust note on the G Coupe is an iconic part of the history of the vehicle," said spokesman Steven Oldham. "Starting with the first G coupe, we felt that a passionate and unique exhaust sound would be a great way to make the car more fun to drive and to engage the customers. We were more than happy with the customer response to the first G coupe exhaust sound and of course have tried to make it better for the new G37."

He added, "The first thing that we have made different is that the exhaust system on this car is completely symmetrical from the engine all the way to the exhaust tips in the back. We also worked on trying to make the exhaust sound more prominent for the driver of the car rather than just the lucky bystanders."

All of the time invested was time well spent, Mr. Oldham added. "After many computer simulations and multiple physical test mufflers, we finally found the one we felt was the best balance of in-cabin sound under acceleration combined with a comfortable sound level while cruising."

Infinitis -- at least in this part of the country -- are not cars you see every day. I think of it as a luxury line for the discerning. People who don't know better may ask you why you didn't get one of the more familiar sporting luxury brands that people flock to like lemmings.

Never mind all that. There's something to be said about being different. And this car says just about all of it.

The Infiniti G37 Coupe is all-new this year, and comes in three versions: Base, Journey and Sport, with prices starting at $34,250. Ours Sport version included sport-tuned suspension, viscous limited slip differential, unique front fascia and side sills, sport steering wheel stitching and aluminum pedals.

Power comes from a 3.7-liter, 330-horsepower V6 rated at 18 mpg in the city and 24 on the highway with a five speed automatic. I averaged about 20 miles per gallon during a week's driving.

When you get into this car, you notice that it comes closer to providing you with a custom designed bucket seat than almost any other car in its class. Everything about the seat is adjustable to your individual taste, including the side and thigh bolsters and the leg extension feature, which includes a moveable portion of the seat under your legs. It's all quite comfortable, though the side bolsters can be a bit tight fitting in some settings.

Hit the switch, and an orange light around the button flashes to the "on" position -- and here comes that exhaust sound! If you're driving at night, a brilliant purple ring appears around some of the controls in the center stack. Beneath your feet, the brushed aluminum pedals toss off a gleam or two as they await your commands.

The sound system, called "Studio On Wheels" by Bose, is fabulous. Infiniti says it's the first system that recognizes that music usually is enjoyed as it comes toward you, so the 11 speakers are placed with that in mind.

Perhaps the only real problems I had with the car came from some of the interior ergonomics. If you're short like me, you may find the high sills of the doors confining and tough to get used to. Women in shorter dresses will want to be particularly judicious. And that rear seat? Don't even think about it unless you're about 2 feet tall.

Still, the G37 Coupe is nearly incomparable when it comes to two-door touring coupe luxury, performance and sportiness.
