Hey Steve, to each his own. Me having 6 cars, is most I would want. It's hard to enjoy them. I try to have some diversity, would not want 5 or 6 69 TAs, as they would all look the same. I have 3 little kids so time limited. Being a caretaker of 100s of cars is not for me. It's almost like these people who take in 100s of strays.
The car I've had the longest is my 1969 RAIV TA, had it since 95. I, like you had alot of cars, parted many 70-2 TAs, & 2 69 TAs.
