Yesterday on German Ebay a 1958 Wartburg 313 Sports Coupe sold at auction for 50,050 Euros. The car was in good (not concours) condition and had about 8 months of TUV (MOT) remaining. These cars had the 900cc engine from the IFA F9 and early Wartburg 311, but with twin carburetors. Only 469 of these cars were produced and some later cars reverted to a single carb arrangement. Obviously this price was exceptional due to the car's rarity, but all 311's nowadays are also rare in good condition. Watch their values soar in next 5 years or so.
