Great lead-off post for this thread! I would have bought a 2016 LR4 if it had been available with the same Td6 diesel drivetrain that the RR and RR Sport had that year. Even though the D5 was new in 2017 I had no hesitation in ordering one since it did have the same proven Td6 diesel drivetrain as the RR and RR Sport.
I'm happy for you LR4 owners for whom appearance is the primary consideration in selecting an off-road vehicle. Though my D5 doesn't look as "off-roady" as your LR4s, its off-road capability exceeds that of your LR4s, and equals that of the new Defender except for approach and departure angles. Furthermore, it has better handling and maneuverability and is much safer and more comfortable at 80 mph (the speed limit on I-15 in Utah) than your LR4s.
When my D5's factory warranty expires next year I'll pay $4,000 to get an extended warranty from Pentagon Federal Credit Union that will cover it to 100,000 miles (no time limit) with no deductibles.
Super. Glad you're happy with it!
