I have a similar problem with my 405, there's not enough clerance between the subframe and the deck to get the trolley beneath.
I've found the best way around this is to use a small bottle jack with a length of wood (mine's about a ft long) under the front cross-member (assuming there is a metal cross-member on these, don't do it if its all plastic) just to raise the suspension. Having done so there's then clearance to get the Trolley under the Subframe.
Obviously, don't attempt to lift the car beyond the suspension travel like this.
