That's right, Chris. In '59 and '60 they were Holiday SportSedans (all one word) and the coupes were Holiday SceniCoupes. Then, in '61 they were Sport Sedans (two separate words, and Sport, not Sports). Then in '62 and through '65, they were Holiday Sports Sedans (two separate words, and Sports, not Sport). A little confusing, to say the least.
'61 and '62 also had [non-Sport(s) Sedan] Holiday Sedans - the one like I had with the small triangular windows in the back. Olds referred to them as vent windows in spite of the fact that they didn't open. In '63 and '64 they kept that body style but changed over to a real fancy interior and called them Luxury Sedans.
And then, there's Town Sedans....
