The Tatra was a Czech manufacturer, reputed for its original concepts due to the talent of the brilliant Hans Ledwinka. Production was very heterogeneous, from economy cars to large aerodynamic rear-engined sedans. The T77 series was marketed from 1934 and was equipped with a 3 liter V8 engine. Production continued until 1938, when the T77A was introduced, with a 3.4 liter V8 engine. This second version, produced only until 1939, is by far the rarer and more sought after of the two, reaching prices in the order of 300,000 euros.
