How to Choose

• Budget: a base C6 averages $36K and a base C7 $48K. A C6 Z06 ($51K) costs about what a base C7 does.
• Interior and technology: the C7 is a massive improvement. The C6's cabin feels a decade older than the C7's.
• Performance: the C7 has more power and better electronics (magnetic ride, performance data recorder, launch control).
• The C6 Z06 with the LS7 7.0L V8 is a masterpiece of naturally aspirated engineering, rare among modern performance cars.
• The C7 Grand Sport is the sweet spot of the C7 lineup: Z06 wide-body looks with the LT1 engine.

Frequently Asked Questions

Is the C7 Corvette worth the extra money over the C6?

For daily driving, yes. The C7's interior, tech and refinement make it a far better everyday car. For weekend or track use where interior quality matters less, the C6 delivers most of the experience for much less money.

What is the best C6 Corvette to buy?

The C6 Z06 is the standout. Its naturally aspirated LS7 (7.0L, 505 hp) is one of the great American engines. It averages $51K in our data, a lot of performance for the money. The Grand Sport ($46K) is the value pick, with wide-body Z06 looks and brakes in a more civilized package.

Is the C7 Z06 reliable?

The supercharged LT4 is robust, but early C7 Z06s (2015-2016) had overheating issues on track. The 2017+ model years addressed cooling. The base C7 with the LT1 is extremely reliable. 2015+ C7 automatics use the 8-speed 8L90; the 2014 cars carry the older 6-speed 6L80.

Will the C6 or C7 Corvette appreciate?

Z06 and ZR1 variants in both generations have the best appreciation potential. Base models in either generation will hold value but meaningful appreciation is unlikely. Over the last 12 months the C6 Z06 moved +11.2% and the C7 Z06 +6.7% in our data.

C6 ZR1 or C7 Z06?

Both make about 640-650 hp from supercharged V8s. The C6 ZR1 is rarer (fewer than 5,000 built) and has exotic touches (carbon-ceramic brakes, carbon fiber body panels). The C7 Z06 is more modern, with better electronics and a more sorted chassis. In our data the C6 ZR1 averages $107K and the C7 Z06 $77K.
