All were 2.0s mfgd in late 75 & most - if not all - were fully loaded with options to help Karmann & Porsche clear out their parts stock & sell at a higher price.
However, after all these years & even original owner personalization, dealers stealing the Fuchs 2L wheels for steelies, etc. - many are no longer fully equipped.
In Fall 75 I test drove one to help decide whether to get a new one vs. the used 3 year old 73 914-2.0 I ended up with, since monthly payments worked out close due to longer loan terms on new cars. In CA the smog really put a hit on the HP, so I was unimpressed. Every 76 on the lots that I saw back then were 2.0s & fully loaded.
Good Luck!
