That’s like me spending $28k on my M and not driving it because it’s MPG’s aren’t all that great. Stupid. Stupid. Stupid.
Sell it as is, take the loss, and call it a day. That’s what I did with the Maxima when I got the M. It had some issues, I took some $$$ off for them, and sold it in just under 2 months (not bad at all).
