Does anyone know where the official jack points are on a 05 Bonny? Are there any down the center of the car that a floor jack can use? It appears there are 3 on the sides of the car best suited for the factory jack.

Only two listed in the manual front and back as I remember. I personally use the bottom of the control arm in the front and coil spring mount in the back. There are many places that can take the stress, it'* a judgment call and avoiding the body pan is a given.

Like Venom mentions... there are alternatives. Depending on what you need to jack it up for would change where I would suggest.

In the front, the subframe is a good location. The aluminum control arms, I might be leary about, sure they would probably handle it fine though. In the rear, there is the support across the tunnel that is very solid.

i did it few times and used the ones John mentioned, they are also mentioned somewhere in the manual. if you cant find it i can post some pics
