It is much ruder and counter-productive to answer questions in that snide accusatory tone as per above. If the Q annoys then simply ignore it. This is not a debate thread.

Better to ask here than inquire at dealer and get salesman's hopes up on potential sale that may not materialize, even if it is their job. But that's values.....

My advice: 5200s over both 5500s and 7Ks.

Good luck and ask away.
