2nd; have a steel jack and stands for home use and AAA for emergencies.
 

Lightweight aluminum jack + 4000 lb car = accident waiting to happen.

jack fell over, tilted and almost smashed my friends head in

wow.

no problems here. used it about 6 times. I've had 3 flats with my car.
 

The other times were rotating tires.

Yes, slipped from under car on a3 and bent...

Just print out all these postings and FedEx them to AOA.
 

Haven't used the jack myself on the A8 (but had used the ones in two previous, smaller, Audi's), partially due to existing warranty that covered tire service and mostly due to the numerous postings on this topic in the past!

Not once and I've used them 30 times or more since 2004.

Not yet, and I've used it for 6 six years to change to and from snows

It's called a 'tommy bar' and it's not expensive

Sort of, my slightly bent one night about two years ago and I havent used it since.
