1975 berber yellow, How many ? Options

[jeffzm]

So been on a search for a clean 2.0. Not officially for sale I was told about a 1975 30 ish K mile California. car that has sat protected in a barn back east for about 10 yrs but driven couple times a year and owned by a retired Pcar mechanic.

Pretty much original he has been the mechanic from original owner since late 70s, so very well documented. Seems like it's getting tougher to find a unmolested no stories 914 like this. An extra cool factor is it's Berber yellow and from my research 1975 is the only year for that color. How do I find out how many in that color were made ?

What's a car like that worth ? I think we are at a deal but just curious if I am on track with what I offered.

Thanks.
