It will still be an economical fuel alternative.
LPG would have to put on 50cpl before you saw it as break even.

And on top of that in QLD they are about to cut the fuel subsidy that is currently in place which would only be level with any LPG price increase aswell.

Also with the upcoming development on LPG vehicles, the economy will improve meaning that they will consume less and in turn cost less to fuel.

Do you think we should also steer clear of electric vehicles because the electricity costs are going up like a rocket???

“big sixes will become as relevant as a steam engine train.”

You said big 6′s were going to become irrelevant.
Of course 6′s will be higher rego (they have always been), but what ever became of buying a vehicle for purpose???

Not everyone that buys a vehicle is a penny pincher.

Also to say small 4cyl diesels are equivalent to big 6′s is a definate sign that you have never towed with anything.

For a fact the I6 tows rings around the Hilux 3.0L diesel.
4cyls arent really that much more economical. Take the closest in size to a large car with a 4cyl in it Camry as a prime example.
Your typical small cars that that offer similar performance to a base Falcon can actually drink more.

I may have gone a bit of the tangent there so to re-cap

You said big 6′s will become irrelevant.
I and many others here feel strongly that if they do become irrelevant, its a long way off because there are a lot of traits in large cars that arent even close to be being replaced by a small car

We bought the Cruzer not just for towing but for where we lived, Goldfields is full of Roos and Emus and are damn dangerous if you hit them . So using the Cruzer for towing was just one advantage .

Happy moving ,something Im not looking forward too once my house is sold. Cost for someone else to move me up the road would be thousands from the stuff Ive got,Ill be getting my brother with his B class license to drive a renter 8 ton truck [several trips yes} and save myself some big dollars

Hate Moving! grrrrrrrrrrrr

How often would you have five passengers in your car on a trip to the Goldie? And how often are you just by yourself in peak hour traffic or running around town? Yes a 6 running at constant temperature and speed will use less than 8 liters/100km on the highway but, that’s not all the driving the average mum and dad do. You would be just as cozy in a diesel Sorento or Soul on your Goldie trip and they get 5.18 liters/100km.

Yes, we will always need the right tool for towing. But what % of towing would the average mum and dad do and what % of around town would they do?
I am about to move house (true story) it will cost me $110.00 an hour for the removals company to do everything in about three hours. Even if I did all the towing/moving myself I would have to own a trailer (or hire, borrow one) according to the discussion I would need a 6 cyl Falcon/Commodore. After you add up the cost of owning a 6, buying a trailer Vs paying someone $330.00 what is more cost effective?. I am not moving once a year. Not to mention I won’t have to break my back shifting furniture.

Seriously wont we always need the right tool for towing ? We still live in a big Country and do leave its City outskirts a few times a year .

Perhaps in the near future the 6 & 8 will be culled but we will need a powerful 4 to take its place {still in a family size car I think} and for it to be more economical than the 6 & 8 to be viable.

Sure petrol or LPG may be $1.20 a liter and it may cost you $60-80 to fill up [from running on empty] however what determines a cars economy [as always] is how much distance you can cover out of one tank of petrol

Ive passed triple road trains in a Landcruiser towing a 1800kg Falcon ,no FWD diesel 4 is going to be able to that safely.
