I'm new to the forum and was interested to see if anyone could help me get an honest valuation for my Uncle's car. It's a 1967 Impala SS 427 with the M-20 4-speed option. It's all original, numbers matching true L36 car and has been sitting in the back of his shop since the early 1970s. It's rust free and accident free and the interior is in perfect shape. The paint is oxidized from sitting so long but is crack free. It obviously needs some attention because it has sat so long, but the engine isn't seized. I looked it up on Hagerty's valuation, but I'm not sure how accurate that is considering they rarely come up for sale. He is interested in selling, so I'm trying to get a value for him and help broker the deal. Any help would be appreciated.
