What they mean is that the lease value are not compareable to what other people are getting on this web site, but for a Audi if you do like the vehicle that is a good car .
You have to check it at different days. Usually better at the end of the month. Plus, It can be used as a gauge to see where leases are. Yesterday there was a Q7 P w 15k miles 36 month $608 month w Tax of 9%. I wouldn’t call that garbage.
Ok that explains it. Could not find very many cars in my area. Only those models you listed. Also the UI is a bit odd, not a dial selector but just a text field to type in. Just my suggestion, add a selector dial for make/model.
