Ive collected heaps of models over about 10 years so may be able to help.
The 67 Coupe in springtime yellow and various other colours is a Greenlight model which are limited runs, pretty average when compared with others for the price of about $120. Only 67 coupe to have ever been done so far to my knowledge.
Classic Carlecables have made some very nice 66 coupes, Red, Black in RHD and Torquiose in LHD (RRP was $195). I have one of these on Ebay at the moment if you want to take a look. Im selling lots of my 1/18 to enhance my 1/1. Item 120400327537
Lots of Fastbacks in 65-66 but all are average when compared to the Classics model.
Shelby Authentics have quite a lot out including Eleanor. $100 or so.
GMP make some very nice race cars as well. Mostly fastbacks. Can get pricey +$200. I have a very nice Mark Donohoe 65 GT350 FB.
Autoart are getting into these as well. Have done a few 67 FB as well. Expect around $120 for these.
1964 1/2 made by Ertl Precision 100 is a great model.
Give Brad and Moira a try at All Car in Scale in Niddrie, very helpful and prices are reasonable, some of the other stores are not.
