Honda S500
The Honda S500 marked Honda's entry into automobile production in 1963, leveraging their motorcycle engineering expertise. This diminutive roadster featured an innovative DOHC inline-4 that revved to an astonishing 9500 rpm, producing 44 hp from just 531cc. The engine used motorcycle-derived technology including roller-bearing crankshaft and chain-driven camshafts. Independent front suspension and a live rear axle provided nimble handling. Despite its small displacement, the S500 could reach 81 mph and offered genuine sports car thrills in a package weighing just 1609 lbs. It established Honda's reputation for high-revving, precision-engineered sports cars.
Survivors are extremely rare and valuable. Verify matching numbers as replacement engines are virtually unavailable. Check carefully for rust - most examples have significant corrosion. Original parts are nearly impossible to source. Look for complete cars even if restoration is needed, as incomplete examples cannot easily be finished. Japanese-market examples may differ slightly from export models. Expect to pay premium prices for running, driving examples. Consider joining Honda S-series clubs for parts and expertise.
