The only way i would accept any option like this is if it was a removable roof panel like the vet has. i just
the lines of the roof. I dont think there is any way to do it and make it look top notch not to mention function for a long time. Tag i do like the idea of a metal panel that would act like a sun roof but i would be afraid that there would have to be a strip of weather striping that would be visible however it wouldn't make that make that much of a deal with a black car like I'm planing on getting, any other car may be unattractive or just plain ugly.
