This is the greatest Corvette ever - and it's only $70,000

The seventh generation of Corvettes was inaugurated by the exquisite Stingray and its 460 horsepower V8.

Read the review here, as well as our 2014 Car of the Year commendation.

We later sampled the convertible version and got a taste of how happy the Vette's engine is when paired with an automatic transmission. It's actually FASTER than with the manual.

We tested out Apple CarPlay on this Vette.

Then cometh the almighty Z06, a 650-horsepower beast — and easily the best value in supercars on the planet.

A little history. The original Grand Sport Corvettes were created by the car's first chief engineer, Zora Arkus-Duntov, in 1963. They were intended to be race cars, designed to run in the 24 Hours of Le Mans.

There haven't been that many Grand Sport versions in Vette's lineage. This is the third time around.

The GS is more Z06 than Stingray in its styling, which is bold and aggressive.

The Corvette badge appears in a bunch of places, such as on the hood ...

... on the tail ...

... inside ...

... and on the key fob.

The Grand Sport designation is pretty subtle, actually, tucked away on the flanks.

This is cool. A small silvery detail on the center stack behind the shifter evokes the GS's history.

That's one of the 1963 cars.

The seventh-gen Vette is very much a sloping wedge, shape-wise. The motorized convertible top stows in about 15 seconds.

There's a slim spoiler.

A hood scoop with slotted venting.

Yeah, this baby is low to the ground. That's maybe six inches of clearance.

Step inside. If you're a tall person, this can be awkward.

The leather, top-stitched seats in our tester were relatively comfy, but they had enough bolstering to make me feel secure during spirited driving.

A bit more Vette detailing.

The seats are both heated and cooled.

Not much in the way of storage. But then again, it's a Corvette.

What the driver sees when he takes the wheel is fairly straightforward. Analog gauges with some useful controls on the steering wheel: audio system (it's a dandy Bose unit), cruise control, phone, voice activation.

I forgot to snap a photo of the infotainment screen, but it's the same as what's on the Stingray. You have CarPlay, plus Sirius radio, Bluetooth connectivity, USB ports, navigation — and of course 4G LTE wireless connectivity managed through OnStar.

On to the engine!

Woof. It's the 6.2-liter LT1 V8 that we find in the Stingray, making 460 horsepower. No supercharger, as on the Z06. But the GS gets a bunch of the Z06's performance goodies, making it the better track car than the Stingray. That's the key difference among the three versions of the this Vette.

The combination of this 8-speed auto with the GS's V8 is the best tranny-engine marriage that can currently be bought with money. It's simply brilliant, enabling a Chevy-claimed 0-60 mph sprint of 3.6 seconds, as long as you're outfitted with the Z07 performance package.

Supercool blacked-out aluminum wheels add a whiff of menace ..

And these Brembo calipers clamp down on the discs to provide ample stopping power. The setup is taken from the Z06.

You can slip in manual mode and use the paddles to upshift ...

... and downshift yourself, but actually, I didn't do that very much. If I have one complaint, it's that these paddles feel kind of plasticky. I didn't like it. So I just let the car shift gears for me. More on that in a moment.

Driving modes are chosen using this toggle wheel.

Wet, for when it's you know, wet. Unsurprisingly, 460-horses piped to the rear wheels can make for a slippy rear end.

Eco! Let's move on quickly ...

Tour, for when you want to cruise around listening to Jethro Tull with the top down. By the way, you can get 26 mpg from the GS in highway driving.

Now we're talking! Sport is the gateway drug. It starts to bring the Grand Sport to life. Most notable is the exhaust note, pumped through four trumpet-shaped pipes. It begins to get ferocious. Everything firms up. The steering becomes alarmingly precise.

Track! Sweet lord. The engine note moves into Ferrari 458 territory: a demonic rumble that gives way to an unholy scream. The full song of a big old V8. The suspension becomes deliciously stiff, and the steering reads your mind.

I spent more or less the entire 48 hours I had the car in Track mode. Let's fire her up!

And we're off!

Yep, I'm smiling. I didn't stop smiling. The Grand Sport induced a near-constant state of joy.

Let's get down to it.

This is the greatest Vette ever. True, the Z06 is mind-bogglingly impressive, and the Stingray is wonderful.

But I grew rapidly addicted to the combo of the 8-speed, the V8, and the suspension dynamics. Over and over again, I let the revs climb slowly north on the tachometer, feeding in a flow of throttle, then abruptly increasing my input. BOOM! The back end LOCKS DOWN, the front rises slightly, and you're off like you've been fired from a howitzer. The power is sweet and honey smooth, but there's so much of it.

And unlike with the 650-hp Z06, where it's well-nigh impossible to get into all that oomph, with the Grand Sport you can sense it enveloping you, challenging and protecting in equal measure.

The handling is sharp and direct, and your sense of the road is immediate. This car feels very much like a Vette, too, with that edge of backwoods wildness that you don't get from a Porsche or Ferrari or Lamborghini. That said, all the Z06 tech on loan means that the Grand Sport is a genuine sports car. Sure, you can haul ass in a straight line all day. But you can also carve into corners. Blissful.

You simply can't get a better high-performance car for the price. It's under a hundred grand! A Ferrari, Porsche, Lamborghini or McLaren would cost you hundreds more. And you don't even need to have Z06 envy. This is the one, people.
