Brand new blue & red convertible cars and says 50’s maybe Thunderbirds 7in long

You are buying both the blue and red cars for 1 price. They are brand new and are convertible. One is a blue car and the other one is red and on both sides says 50’s. (I think it is a 1950 Thunderbird but not sure). Comes from a nonsmoking and pet free home. Trying to help pay for my dads cancer bills. Prices are negotiable. These cars have never been played with just collected. Each car is around 7 in long.
