The Corvette sells well in the US because it's an American icon. The modern Corvette has up to date tech, which is for the car magazine writers. The buyers are mostly buying them because of the history of the car. The Corvette has been the American sports car that was in the same performance range as the top names from Europe for decades. They sell some overseas, but it's kind of a novelty.
Outside the US Corvette can't compete for prestige with brands like Porsche. Even if an argument could be made that the Corvette is a better driving car. (I don't know one way or the other, I've been in Corvettes, but never drove one and I don't recall ever being in a Porsche.)

Off-Topic
Starting in 1997, Chevrolet declared war on the old school sports cars but only after firing a warning shot across their bow, the 1990-1995 C4 ZR1. For many years it held it the record for miles covered in 24hrs, (
[email protected] average mph for 4,221.256 mi, World Record). This pissed off the Euro old guard and made them up their game. Europe ramped up their power and dropped weight, and raised prices in anticipation of the C5 Corvette that was coming soon.
But they brought a knife to a gunfight. The LS1 Corvette just pissed in their punchbowl. They best they could come up with, was "it uses American Plastic for the interior instead of German or Italian plastic!". They were hoping '97 C5 was a Halo Car, a One-Trick-Pony.
Unfortunately for them, the 1997 retail LS1 Corvette was just the test car. Next came the Z06 FRC variant. And it's been Corvette ever since. The Corvette has been untouchable in it's price range for 20+ years now. To hang with the Crossed Flags, you need to bring about $250,000 or more to the table. Ford has upped the ante this year to $453,750 to produce a Vette Killer. It has beat a Vette endurance racing this year.
So perhaps modern Vette buyers are Walmart shoppers. Why spend $250,000 when you can get a better sports car for $65k?
Even the $125k C6 ZR1 was a bargain when compared to what it brought to the table. A serious threat to any OEM car on the track, regardless of price. And oh so sweet to drive. A real driver's car that goes over 200 mph but is never scary.
And the Vette is getting a WHOLE lot faster very soon.

But that was last century.
What does a discount Chevy kid's car (Camaro) do as sold?
7m16.04s at the 'Ring. This is faster than most Ferraris, Lambos, and Porches on one of the world's most grueling tracks. But it's a 4 seater that sells for chump change.
