The Limited models made their debut in 1982 and ran through 2002. They were the top of the line in terms of standard features and options available. After 2002, the Classics became Classic Limited with the two models combined into a single model. The Classic series came into being in the early 90s around 1992 and replaced the Excella model which had been the gold standard exceeded only by the Limited model from the early 70s through the early 90s. During this same time period the slightly cheaper models were marketed as the Sovereign
model where as until this year the base models were known as the Safari line. There is a list of models produced over the years on this site, but I can't seem to locate it at the present time. If I find it, I will post it later.
