The Austin-Healey 100-6 succeeded the original 4-cylinder 100 in 1956. It introduced a longer wheelbase to fit small rear seats in the BN4 2+2 model and debuted the BMC C-Series 2.6L inline-6 engine. Early cars were noted for being less powerful than the outgoing model, but a revised 6-port cylinder head in 1957 boosted output from 102 to 117 horsepower.
Collectors appreciate the 100-6 as the first of the six-cylinder "Big Healeys," offering a classic British roadster experience for less money than the later 3000 models. The two-seat BN6, produced from 1958, is rarer and often more sought-after by purists than the more common BN4 2+2. Its graceful lines and eligibility for vintage events make it a staple in the classic car world.
The market for the 100-6 is well-established, with an average price of around $32,500. This positions it as an accessible entry point to Big Healey ownership. While top-tier restorations can exceed $60,000, project cars are available for much less, offering a solid platform for restoration enthusiasts.
Buying Tips
- Rust is the primary concern. Thoroughly inspect the chassis frame, outriggers, sills, and floor pans, as repairs are costly.
- The post-1957 engine with the 6-port cylinder head is more powerful and desirable. Check any engine for signs of overheating, a common Healey issue.
- Test the Laycock de Normanville overdrive unit if equipped. It should engage and disengage smoothly in 3rd and 4th gear and is essential for highway driving.
- Aluminum front and rear shrouds are expensive to repair. Check for poor panel alignment and excessive body filler, which indicate past damage.
- Decide between the 2+2 BN4 and the rarer 2-seat BN6. The BN6 commands a slight premium for its cleaner profile and lighter weight.
Sale prices range from $1,350 for project cars to over $60,500 for excellent, restored examples.
