Well if you are in PS you can almost certainly do a mileage upgrade for 45k instead of 135k (you have to call). To me there is no way D1 is worth 135k especially ex-SEA.
If you PWM from all reports it will not count towards your MQD total.
If you want DM I would just pay for the upgrade, otherwise I would stick with PM and call in about doing a MUA for 45k
