Hello and maybe I can help as James has opted out. Can I ask why you are replacing the shocks? Also can I get the last six of your VIN number? It will be G then 5 numbers.
The shocks are not covered under the select edition warranty because they are considered a wear item. If one of the shocks is leaking it can cause the system to lose air pressure and will feel like a bad roller coaster ride. You should make sure they check the air compressor as if it has to constantly pump the system up because of a leak it can fail. The price you received seems high by about $100.00 unless they included a diagnosis fee.
