Front interior room seems wider and higher. Vehicle is faster and more responsive than the LS 430. Leather work is craftsman style as in the SC 430. Enjoying the satellite radio. Strong climate control. No wind noise. The engine is now audible at idle. 8 forward gears. Came with Bridgestones not Dunlops: runs straight down the road - no wandering drift. Stronger brakes than the LS 430 . Easier steering. Larger view from backup camera . This car is a 10. Nothing negative!
No true difference in the normal model and the "L" model. Fact is the "L" has a slimmer turning radius.
