My dad has finally decided to retire, and his and mums plan is to spend 6 months of the year here in Aus and 6 in UK - with the Aus months being spring summer here and being grey nomads and doing the whole country over a couple of years.

Dad wants my input on car selection (he is coming in June for 5 weeks and looking to buy car then and hire a trailer tent to get a few ideas), as we will have use of the car plus trailer tent when they are not here (autumn/winter) - I know nothing about cars, we have a Corolla and use public transport most of the time, which will continue unless we need to move more people around or go away for weekend etc - when we got ours I got it because had a Corolla at home, we went out one morning 4 years ago and bought it, I didn't try anything else - so really am clueless. I have owned a Ford Fiesta in the UK and a Corolla there and wouldn't buy Ford in UK again on that experience but not sure if that is relevant here.

He will buy pre-owned but is looking for only a year or so old, and look to sell it on at somepoint (maybe to me so we can do our year round Oz if I can wangle it).

Any suggestions, advice? He has a Prius at home (so fuel economy and environmental friendliness are quite important to him but for the amount of KM's and the towing will have to compromise on this a bit). He likes the idea of seven seats so we can all get in it, but also most of the time would be just him and mum.

I expect they will want to go off road a bit but suspect would only say be about 10% of time.

I want to help him as he is in UK so no real local knowledge and will be great for me too - but it makes my headspin :-)
