Buying Guide for Your Used C6 Corvette

Buying a Used C6 Corvette?

The sixth generation of the Corvette, known as the C6 (2005-2013), was a significant step forward for the model. It retained the classic Corvette formula of a front-engine, rear-wheel-drive layout with a powerful V8 engine, but it introduced a host of improvements. These included a more refined interior, updated technology, a stiffer chassis, and a larger, more powerful LS2 engine. The C6 also marked the return of exposed headlights, a design element absent since the 1962 model.

Top 10 Tips for Buying a Used C6 Corvette:

1. Thorough Undercarriage Inspection: Get the car on a lift and inspect for leaks, damage, and signs of improper jacking or bottoming out. Pay close attention to the rockers, fenders, and front bumper. This checks for underbody damage.
2. Fluid Check: Check all fluids, especially the engine oil and clutch fluid. The clutch fluid is often neglected and may be dirty. Pay special attention to the clutch hydraulics as a potential weak point.
3. Signs of Modifications: Look for signs of recently wrenching or removed modifications, such as wrenched bolts on the manifolds, intake, and throttle body.
4. Test the Transmission: Shift through the gears at high RPM to check for transmission issues to ensure the synchronizers are functioning correctly.
5. Listen Carefully: Listen for noises and unusual sounds from the engine both at idle and while driving.
6. Tire Condition: Check the tires for adequate tread life and even wear.
7. Run a CARFAX Report: While not always comprehensive, a CARFAX report can reveal potential red flags and service history.
8. Inspect for Cosmetic Damage: Check the wheels for curb rash and the seat bolsters for wear, especially on the driver’s side.
9. Check and Test all Electronics: Test the heat and A/C, HUD and C6 Corvette Infotainment System, and headlamps.
10. Address Specific C6 Issues: Be aware of common C6 issues like harmonic balancer problems and potential targa top creaking.

Bonus Tip: Don’t fall in love with the first C6 you see. Take your time, be thorough, and don’t be afraid to walk away if something seems off. There are plenty of C6 Corvettes out there!
