What appear to be patent drawings of numerous SEAT models were found in a posting on a Spanish blog called Decoches. Unfortunately, no additional information is provided about the source of the pictures.
A quick research on the European patent office didn't return any results, so we're not going to brand the sketches genuine just yet - for all we know they might be the work of an independent designer / artist who has nothing to do with the VW Group-owned, Spanish carmaker.
In any case, you can check out all the drawings / proposals for a series of SEAT models in the gallery after the break.
