I agree with everything good about the R-32,
but the R-40 is an icon too, in its own way. They were the first new cars to run on the E and F lines, (starting in 1968) since those lines were built in the 1930's !! Up 'til then those lines had only ever seen the (by then) tired old R-1 thru 9's.The first time I ever saw a new R-40/Slant come flying into the Union Tpk. station on Queens Blvd. in the Spring of 1968, it was like stepping aboard a space ship; the difference between those shiny new Slants and the grimy old cars from the 1930's was so striking; I'll never forget it. So let's nobody knock the now tired, worn out R-40/Slants; they were like science fiction in their heyday.
BTW, I too like the blue/white interior of the R-160's. They do have a comfortable ambience to them. Not unlike (chuckle!) the R-40/42's when they were new. They had an aqua colored interior, which (sadly) gave way to the dull gray and beige when those cars were rebuilt. I'll never understand why they didn't keep that nice aqua color or something similar.
