hydraulic bottle jack at LEAST 2 tons lift capacity - cheap, easy to get, goes i nthe spare wheel well and ANYONE can get eh car up (also square of 18mm board to place underito n soft gorund)...oh and an extending wheel wrench to break the lug nuts free....

with those my 4yo could change the wheel...(well perhaps not but you know what i mean!)

FYI my delica has a bottle jack as standard and that weight in at 2500kg!!!

I have a floor jack and jackstands.

I'm somewhat embarrassed to say that I have an extra Volvo jack in my garage that I use for snow tire changes. I like the fact that it can lift two wheels at once. I do put jsckstands under the car. Quickly. I'd suggest a board under the jack on uneven ground.

I also carry around an air pump in the car and have AAA. There are multiple sources for heavy-duty scissors jacks.

Using my floor jack to lift both wheels is great for tire rotation. When my daughter started to drive, I bought her a AAA card and a cell phone. She isn't strong enough to break the lug nuts loose by herself anyway.
The trunk jack is worthless, along with the temp spare. Get a flatbed tow and have the tire fixed/replaced.

Hell yes I have an issue with mine. I own two 97 850 wagons. If you try to use that damned jack on soft ground, what it will do is slowly kick out from under the car and let the car down onto the threaded portion of the jack, scarring or cracking the plastic door channel. It did it on both of my 97's. What a worthless piece of crap. No, I don't know if there is a carry-round replacement. Apparently your only option is a roll-around floor jack, which won't help you much out in the boonies. Dick

Were you aware that there was a recall early on? Even the new one is not great though. The driveline of the car being rather loose (like many other cars), I put extra chocks on the side that's not being raised.
