Floor and stringers
 

The 1998 Mariah promotional video show Mariah went to fiberglass floor and stringers. I had a 1998 202 and a 1999 222 and currently have a 1999 212. The 202 and 222 both had fiberglass floor with snap in carpet. My current 212 has glued in carpet and it seems to have a wood floor but behind the back seat is fiberglass lined. Are all of these just randomly built different?
