What is a 1955 Austin-Healey 100 100M worth today?
The Shifty Estimate is $108,800. That sits above the $92,050 median of actual sales because the median counts every car that sold, including high-mileage examples, while the estimate describes a clean, low-mileage one bought today. We rate confidence medium: 6 public sales in a year is a thin market, and the spread between them is wide.

The 100M transformed Healey's sports car into a genuine performance machine, with factory modifications including a cold-air box, larger carburetors, and higher compression ratio boosting output to 110 horsepower. Only 1,159 examples received the Le Mans modification package, making the 100M significantly rarer than the standard car. The distinctive louvered bonnet, leather bonnet strap, and competition-style wire wheels announced its sporting intentions, while the improved four-speed transmission enhanced drivability. Built during 1955-1956, the 100M bridged the gap between the standard car and the ultra-rare 100S, offering enhanced performance with reasonable accessibility. The Le Mans connection adds motorsport cachet, as these modifications were inspired by the factory's racing program. Today, genuine 100M examples command strong premiums over standard cars, with collectors appreciating their perfect balance of performance, rarity, and period racing heritage.
