Widdly- I have a Steelcraft Strider DLX (which have now been
replaced with the Strider Plus). It has solid tyres, 3 seat positions, large hood that pulls down quite far, adjustable handle height, reversible seat and you can also buy the capsule and bassinette to make it a travel system.
It is quite large to fit in the boot but we have a Holden Commodore and it does fit so it will fit in a falcon.
It is stable but you can't put a nappy bag over the handles.
I love mine. It's got a massive shopping basket too!
