I gues a 6-cylinder GT Hawk is a pretty rare thing in US whereas especially on the continental Europe many cars were fitted with 6 cylinder + 3 speed OD -- no power stereing or brakes. There are continuously several cars for sale. Owners ofcourse follow the prices of eBay and also may lookm at NADA or Old Cars Value guide recomendation on just to deduct 10 % due to 6-cylinder. Well I have looked and driven some 4-5 6-cylinder GT Hawks ( have also owned one very nice 1959 Silver Hawk 6-cylinder) -- I think ( personally) that the value of a typical "no optioned" 6-cylinder GT Hawk would be somewhere 25-40 % lower than the V8 model. It just feels totally different different ( I have also owned 3
1962-1963 GT Hawk -- all were factory original 4-speed cars with HD suspension , TT etc). I have this question as I have badly rusted 62 GT Hawk with 289 + 4-speed + 44 TT rear -- but thinking about buying a 6-cylinder car to convert it I just feel that the
6-cylinder cars over here are "overpriced" ( based on the 10 % lower bookvalue vs. V8 models) ... there are still quite many things in the brakes, rear axle, suspension, cooling etc. that I dropped the idea.
I can easily buy the view of adding 15 % value on a 4-speed option ... but the proposed 10 % deduction on 6-cylinder ( on 62-64 GTH) feels way too little to me.
