Toyota Hiace regius 1999 model

[JC4]

Hi, I am looking to buy a Toyota regius 1999 model. I need to fit 4 child seats in (2 baby capsules and 2 toddler seats nb: not boosters) Can anyone tell me how many anchor points are in it and what the configuration would be to fit them in. (ie 2 front 2 back or 3 back and one front). Any info regading how good this car is would be great. Thanks in advance. JC4
