Selling a 1956 Austin-Healey 100M

1956 Austin-Healey 100M

One of the most intriguing Austin-Healey classics, the Austin-Healey 100M Le Mans edition was manufactured from 1955 to 1956, with approximately 680 factory-built examples released to the public. These Le Mans editions would offer larger carburetors, a cold air box to increase airflow to the carburetors, a high-lift camshaft and higher compression pistons to increase performance and power. Externally, the 1955 and 1956 Austin-Healey 100M would feature a louvered hood and bonnet belt, and in many cases, two-tone paint. While the factory-built Austin-Healey 100M models are quite desirable, there is also a selection of 100M models that were built as kit conversions – installed either by the dealer or the owner. It is estimated that approximately 500 of these kit conversions were sold and featured all of the upgrades except the higher compression pistons. While all factory-built models are BN2 series examples, the kit conversions could be installed on both BN1 and BN2 models. As one might expect, the original factory-built examples command the highest values, while those that are conversions fetch slightly lower price tags. Nevertheless, buyers are looking for Austin-Healey 100M models of all types and conditions.


1956 Austin-Healey 100M Seller’s Guide

In order to authenticate your particular 1956 Austin-Healey 100M as an original, educated buyers will be looking for a few things. First, they will expect the louvered hood, bonnet strap and high compression pistons as a sign that the car is factory-built. Next, they will want to verify the body number of the car, which can be found on a plate on the firewall as well as on the hood, on the boot lid retainer, on the front splash panel and on all four of the cockpit surround alloy trim pieces. Once found, comparing this number to historical records can indicate whether or not your particular model was factory-built. If your classic is not factory-built and was actually a kit conversion, it is still valuable in the market, but factory-built examples certainly get the best values. Another very important Seller’s Tip is to allow serious buyers to perform a third-party inspection with a qualified Austin-Healey mechanic. If you’re unsure of who to trust, the Alex Manos team can point you in the direction of qualified inspection companies throughout the United States.
