I have driven both. I own a roadster. Blind spot is there. With top down
much better, of course. I have just learn to put mirrors way out. It is hard to get used to at first, but that is why you have the interior mirror.
I have taken my car on 7-8hr cruises. I find it more comfortable on my back than any car I've driven. I don't think I could own an SRT in the east. Our roads in the west are excellent. No pot holes.
