Had a search seen about the mangled sills due to sloppy jacking but cant find a definitive where to place your jack thread bar on the silks With the Gp (corsas clone as maxxi calls it) the hand book only shows the sills however there are 4 other points under the car used in the workshop just wondered if the 500 is the same ?
A 500 in the company of a trolley jack is about as safe as a chicken in the company of a wolf. A lot of cars have been damaged out there and I've heard an anecdotal rumour that AA patrolmen have been instructed to use only the jack supplied by FIAT when wheel changing at the roadside.
FIAT's official technical documentation is hopeless - it just says to use a 4 post lift on the workshop jacking points & absolutely forbids jacking on either the front wishbones or the rear axle.
If you use a trolley jack ANYWHERE on the outer sills, even at the arrowed jacking points, then you'll most likely damage the car. I know from experience that some main dealers raise the car on the inner sills at these points, but this too can cause some (admittedly superficial & non-visible) damage, & it just feels wrong to me to lift a car this way.
So I've had to work this one out for myself. What follows is entirely my own work, it's not endorsed by anyone; so use it at your own risk. It's served me well, though, & I've not had any problems since getting the car.
There are fairly obvious reinforced sections of bodywork at both front and rear (photos attached) on which the car can be safely raised on a trolley jack PROVIDED you use a suitable pad with it. Professional quality trolley jacks often come with a hard rubber pad, which should work fine. If you buy a cheap DIY jack, though, you'll need to improvise something & so I got the router out to fabricate something out of a bit of hardwood I had lying around (more photos).
Be aware that the car could slip off the pad if it's not on a reasonably level surface, so chock the wheels & always use axle stands if any part of you is planning on going underneath the vehicle.
BTW all these comments apply equally to the Panda.
