There are many people saying all the Porsche models are just too common and expensive, but you know what guys? This one is totally different, and it’s actually a pretty affordable Porsche,that’s right: affordable Porsche. In the pictures below you’ll see the restored 1957 Porsche diesel-engined Allgaier tractor. Yours for an estimated $12,000-18,000 at auctioneers Historics at Brooklands’ November sale, it’s the kind of Porsche you just don’t see every day. Alongside Ferdinand Porsche’s businesses building Porsche cars and the Volkswagen Beetle during the 1950s, he also built tractors. His company built some 120,000 of them as Porsche Allgaier models before buying the latter company outright in 1957. This tractor, therefore, is one of the last associated with the Allgaier name.
