Will be interesting to see what Toyota releases for bringing LC back.
300 series exists as LX600, but no LC since cancellation
Some rumors that it will be similar to the announced GX550, which is being considered a 250 series. The interesting thing is that the GX550 dimensions appear to mirror very closely the 200 series whereas the 300 series is overall larger.
For those buying used, part of the reason for price difference between LC and LX is production volume. Around 3k LC sold for any given MY whereas 6k+ sold of LX for similar MY. More available, and LX were often babied by owner. Biggest difference aside from cosmetics is suspension. LC is traditional + KDSS. LX uses AHC which is actually a hydraulic system. It's proven to be very durable and impressively maintainable. Generally set and forget aside from fluid flush ~60k miles and accumulator replacement ~120k.
Nice part with AHC is you can gain an inch+ of lift with a 10mm socket. Height is controlled with sensors. Takes about 10 minutes to change sensor position to gain height etc.
