G6 77”

Just ordered thru LG Partner Store for $3351 w/ tax. This includes G6 and 42” C6. I am paying Abt to professionally install G6 with supplied flush mount. They will conceal in drywall HDMI cords to sound bar and Apple TV. I have a 30” tall media console and plan to mount G6 at 38” from the floor with 3” sound bar resting on top of media console. Cost of install is $500, which includes recessed outlet box for flush install. I hope/plan to sell the 42” C6 for $600-800 locally to effectively make G6 cost ~$2300-2400 pre-tax, thoughts? I’ve been monitoring for a while and while the partner store has offered several “freebies” the C6 felt like the most substantial and something I’d either use or sell quickly. I understand I’m mourning the TV a little high but I have 9’ ceilings and want a gap between sound bar and bottom of TV.
