What F1 issues?
I don't know what F1 "issues" you're referring to. I drive my 360 F1 coupe regularly (3-4 times a week, 20K miles so far) with no issues whatsoever. As a matter of fact, the more I drive it the better/smoother/slicker it runs including the F1 transmission. Normal scheduled maintenance only.
I think the 430 F1 is also a great car (although not as nice looking) and will serve you well when properly cared for, but I doubt maintenance costs are significantly different in the long run.
