I use a trolley jack and axle stands at home ..... I intend to replace the scissor jack with a bottle jack ..... only downside of the bottle jack as a 'roadside' jack is that they are a bit heavier than the scissor jack ...... trolley jacks are available (at a price) in alloy for motorsport use but I have yet to find an alloy bodied bottle jack. I seem to remember reading (possibly on here) that Porshe cars have a nice quality alloy scissor jack .... these can be found on ebay not too expensive ... perhaps a forum member who has one could comment on the weight and ease of use.
Strange to supply a car with a spare wheel but no jack to fit it (can understand no jack if the car has no spare, just a repair/inflate aerosol) .... I know the AA/RAC will fit your spare at the roadside, but with the wait you have for them anywhere vaguely remote I don't fancy that as an option

Bought one a few years ago, not yet used in anger but it has been tested in the garage under load & was ok, much lighter and more compact than the OE steel one, I also carry a small plywood pad just in case of soft ground
