Personally, I dig the Cayenne and I am not too crazy about the 987 or 997. Most likely, my next vehicle purchase will be a Cayenne.
Similar to what Tool Pants said, the purpose of any company is to make money, a quick look at the PCNA sales number will show you that is sells big time.
One downside to the Porsche tractor, and Cayenne for that matter, is that PCNA will not let you race them in club races
