It certainly looks hot. It may even be fun to drive (I haven't driven one, so I couldn't say). But I'll bet there are some modern cars that are more fun to drive for the same (or lower) price.
I'm going to take a semi-educated guess that the ZL1 originally sold for $10,000 in 1969. The equivalent amount of money today is about $53,000. What kind of sports coupe could we buy for $53,000? Let's find out.
We could get a Porsche Boxster S for about $53,000. However, Porsches are overpriced, and the Boxster S only has 280 HP. Let's look elsewhere.
We could get a BMW M3 for about $54,000. It has 333 HP, and handles like a dream. Still, we can do better.
We could get a Lotus Exige for about $51,000. It's only got 190 HP, but I guarantee it will be more fun to take to a track than any street car from the 60s. This car is reputed to have nearly telepathic handling.
We could get a Mercedez-Benz CLK coupe for about $54,000. It's got about 300 HP, and is luxurious as hell.
We could even get a modern Corvette for $45,000. The 2006 model has 400 HP and, thanks to tire and drivetrain advances made in the last 35 years, would beat the old Stingray on any track on the world. It gets 26 miles per gallon on the highway! You'd even have $8,000 left over to spring for a turbocharger/supercharger to widen the performance gap.
Now, I will admit that none of these are as cool as the old Stingray. They are, however, better cars.
