Not a CHANCE, Bob ... :iconwink: :lol: :rotfl:.
She would never even contemplate allowing it ...
A few things to bear in mind about the SH vs the series II SG:
1) The SH is a considerably larger vehicle than the SG. In fact, it is almost identical in size to a Ford Territory. This can be a plus or minus, depending. I prefer my SG, but SWMBO prefers her SH ...

. The SH has a longer wheelbase than the SG/SF. The extra space is in the passenger room, not the cargo area, which is a bit wider, but little, if any, deeper than that in my SG. The SH also loses a little height in the cargo area due to the 225x55 17" spare, making the boot floor a little higher than it is in my SG - but then, the ceiling is much higher in the SH ... .
OTOH, one does not need to amputate the feet of any adults getting in the back of the SH, as one does with the SG ... :rotfl:. The rear doors of the SH are also longer than the SG.
2) The SH has got more ground clearance than the SG to start with. Around 20 mm more, IIRC. Perhaps less need for any lift?
3) After the MY10 model, the SH lost the SportsShift auto (I think ... ); and also the EJ-253 engine. The later model SH's had the FB engine. Personally, I think that the last of the EJ N/A series engines - the EJ-253 - is a better sorted engine than the FB engine in many small ways.
4) From what I have observed, the SH is probably a bit safer car than the SG, after one has hit something ... . It has the very important structural differences of having the "hooks" at the rear edge of the bonnet that lock it down in a front end stack; and also has the door frame bolts at the bottom of the rear doors. My SG hasn't got either of these.
The SH also has side curtain airbags as well as the front side impact bags - i.e. 6 in total vs 4 in total. The side curtain airbags in the SH protect heads in the rear seats as well. Both have the active head rests.
The SH also has VDC on top of the EBD and ABS in the SG.
OTOH, I don't think that our SH handles quite as well as my SG ... Not quite as stable, as distinct from grip. Still far better than our old Camry - but a subtle difference between the SH and SG.
Just a few thoughts. Happy New Year, and good hunting.
