The split window is a distinctive design feature that appeared on Chevrolet Corvettes for only two model years: 1963 and 1964

A split window Corvette has a rear window divided down the middle by a vertical bar, creating two separate panes instead of one continuous sheet of glass. This design ran only in 1963 and 1964 on the second-generation Corvette (called the C2). The split window is one of the most recognizable features in American automotive history, and it makes those two model years when ready identifiable to anyone familiar with the car.

The split window was not a cost-saving measure or a structural necessity — it was a styling choice. Designer Larry Shinoda included it as part of the overall C2 aesthetic, which emphasized a sleek, jet-age look. Chevrolet dropped the split window after 1964 in favor of a single rear window, and that decision has made split-window models far more sought after by collectors ever since.

Key Takeaways

  • Split windows appeared only on 1963 and 1964 Corvettes and are one of the most distinctive design elements in the car's history.
  • The feature was a styling choice, not a structural requirement, and Chevrolet removed it after 1964 in favor of a single rear window.
  • Split-window Corvettes are significantly more valuable than later models, and prices vary widely based on engine size, condition, and originality.
  • The 1963 model year is rarer than 1964, which affects both availability and collector demand.

Why the split window became so valuable

The split window's two-year run created scarcity. Chevrolet built roughly 10,600 Corvettes in 1963 and about 19,000 in 1964, but not all of those survive in good condition. Once collectors realized the split window would not return, demand for those specific years climbed steadily over decades.

The rarity is compounded by the fact that 1963 was the first year of the C2 generation, and 1963 models are harder to find than 1964s. A 1963 split-window Corvette in good condition commands a premium over a 1964, all else being equal. The split window has become so iconic that it is often the first thing mentioned when someone describes a classic Corvette to a non-enthusiast.

How split-window models differ from later Corvettes

Beyond the rear window, 1963 and 1964 Corvettes have other design details that set them apart from the 1965 and later models. The 1963 model year introduced the C2 body style with a new fastback roofline, a different front end, and a revised interior. The 1964 kept most of these features but made minor refinements.

Starting in 1965, Chevrolet redesigned the rear window as a single pane, changed the rear body panel, and updated the interior again. These changes were significant enough that a 1965 Corvette looks noticeably different from a 1964 when you stand them side by side. The split window is the most visible marker of the earlier design, but the overall proportions and details of the 1963–1964 cars are distinct.

Engine options and performance in split-window years

Both 1963 and 1964 Corvettes came with a choice of engines. The base engine was a 327-cubic-inch V8 with 250 horsepower. Buyers could also order a fuel-injected 327 with 300 horsepower, or a 327 with 365 horsepower. A few 1963 models were built with the older 283-cubic-inch engine, but these are rare.

The engine choice affects both the car's performance and its value to collectors. A split-window Corvette with the high-output 365-horsepower 327 is more desirable than one with the base 250-horsepower engine, and prices reflect that difference. Matching numbers — meaning the engine, transmission, and other components are original to the car — also increases value significantly.

What to look for when examining a split-window Corvette

If you are considering a split-window Corvette, the condition of the fiberglass body is critical. Corvettes of this era are made of fiberglass, which can crack, fade, or delaminate over time. Check the body for cracks, especially around the doors and along the seams. Look at the paint for fading, particularly on the hood and roof, which get the most sun exposure.

The interior can be expensive to restore. Check the seats, dashboard, and door panels for cracks or deterioration. The split window itself should be intact — replacement glass is available but not cheap, and a cracked or missing original window reduces value. Rust can also be a problem in the frame and suspension, so have a pre-purchase inspection done by someone familiar with Corvettes if you are serious about buying one.

Originality matters to collectors. A split-window Corvette with matching numbers (original engine, transmission, and other key components) is worth more than one that has been modified or restored with non-original parts. Documentation of the car's history, including the original build sheet if available, adds value and helps verify authenticity.

Price ranges and market factors

Split-window Corvette prices vary widely depending on condition, mileage, engine size, and originality. A 1963 or 1964 model in fair condition with moderate mileage might sell for $60,000 to $80,000, while a well-maintained example with low mileage and matching numbers could reach $120,000 or more. Exceptional examples — particularly 1963 models with high-output engines and documented history — have sold for significantly higher amounts at auction.

The market for classic Corvettes has remained relatively stable over the past decade, though prices do fluctuate based on economic conditions and collector interest. A split-window Corvette is generally considered a solid investment compared to many other classic cars, but it is not a may provide path to profit. Buy one because you want to own and drive it, not solely as a financial speculation.

Frequently Asked Questions

Is a 1963 Corvette more valuable than a 1964?

Yes, generally. The 1963 was the first year of the C2 generation and fewer were built. A 1963 in comparable condition to a 1964 typically commands a higher price. However, condition, mileage, engine size, and originality matter more than the year alone.

Can I replace a split window with a single pane window?

You can, but it will reduce the car's value significantly. Collectors prefer original split windows. If the original window is damaged, replacement split-window glass is available from specialty suppliers, though it is more expensive than a single-pane replacement.

What does "matching numbers" mean for a Corvette?

Matching numbers means the engine, transmission, and other major components are the original parts that came with the car from the factory. This is verified by comparing the vehicle identification number (VIN) and component serial numbers to documentation. Matching-numbers cars are worth significantly more than those with replacement engines or transmissions.

How much does it cost to restore a split-window Corvette?

Restoration costs vary widely based on the car's condition and how much work is needed. A basic restoration might run $30,000 to $50,000, while a complete frame-off restoration can exceed $100,000. Get quotes from shops experienced with Corvettes before committing to a project.

Are split-window Corvettes reliable for driving?

A well-maintained split-window Corvette can be driven regularly, though it is a 60-year-old car with older technology. Parts are available from specialty suppliers, and many mechanics are familiar with these cars. Plan for regular maintenance and expect occasional repairs, as with any classic vehicle of this age.
