No such thing as a standard 76, all are customised.
Ours is kitted with air con, full SPIFR, EFIS, every gadget known to mankind, and it weighs in at 8200 lb empty, 11700 full.
Burns 700lb/hr at 70% cruise and 140Kt or 800lb/hr at 80% and 145-155kt. Fuel capacity is 1800lb, endurance is only 2 hr 20 to dry tanks, so don't get into any IFR holding.
Took out one row of 4 and installed wider seat benches, so we carry 8 in comfort facing forward plus 1 in the front. We chose against the rear-facing club car config because we lose 2 seats and the pax don't like going backwards.
Marvellous machine, lots of guts, FADEC makes it almost idiot-proof, but it is sadly rear-heavy - watch your CG.
