Just thought I would list the alternatives
Mitsubishi Outlander -- As your looking at the 7 seater that's about $37000 -- Comes in both Diesel and Petrol with auto options and the 7 seater option are in the 4WD versions by the look of it.
http://www.mitsubishi-motors.com.au/vehicles/outlander -- pricing seems reasonable
Honda Odyssey -- About $38000 On Road -- Probably the nicest looking people mover on the market IMO -- only in 2WD, but if you are only using the vehicle on road only this could be a nice selection and the pricing is not too bad.
http://odyssey.honda.com.au/Proton Exora -- Very sharp pricing (about $26000 On the road) and
5 years free servicing , 5 years road side assist, 5 years warranty
http://www.protonexora.com.au/ 2WD only -- on road only -- Don't know a lot about these, but at it's price it could be a winner.
Mahindra XUV500 -- About $30000 In Diesel and Manual only (Might be off your list as it's a manual only option)
http://www.carpoint.com.au/used-cars/MAHINDRA/XUV500/model-make.htm comes in 4WD and 2WD version -- Probably the cheapest with AWD ability, that's if you like to do something offroad, may be towing.
Ssangyong Stavic -- About $30000 -- was voted the most ugly vehicle at one stage -- but they appeared to have fixed that now by the look of it now.. Could be a good option if you want a lot or room
http://www.ssangyong.com.au/showroom/stavic 2WD only -- It could be a bit large, but your kids will love the extra room.
Kia Carnival -- About $40000 -- When looking this one up, I was a bit surprised about expensive it was
