I am planning to purchase an 03-06 year model Viper and wanted to know if there is any noticeable difference in the amount of headroom available in a coupe over a convertible or if it is the same? I have not had the opportunity to drive both yet and make the decision that way. I prefer a coupe, but I am 6'3" tall, so the Viper with the most headroom available will be my first choice. Thanks in advance for any info on this subject.
