L400 is 2.8 People carrier shell on shogan/pajero running gear. Or 3.0 v6
L300 is 2.5 mid engined scooby wagon.
Usually auto, but can get manual, come in high roof and low roof, lwb and swb (swb is longer than a lwb fronty) spec varies depending on what optional extras were put on in Japan.
The deli i had was more thirsty than my v6 fronty, but would quite happily tow my frontera behind it on a trailer. (there is no known towing data in terms of weight limits so be careful)
Very flexible use of space look at seating options that suit you before commiting.
Check with insurance before buying as it is an import so some companies wont insure. Also mine was an 8 seater so some companies wouldnt insure for this reason but you can get 7 seaters.
