I think the shops are correct on the over sized tires causing stress that is a general event on all VX. Unfortunately I have done a project like you are facing though not on a VX. You can pretty much count on the VX needing all the work the shops are telling you and probably several more. The shops probably stopped looking after finding a couple of grand so as too not price themselves out of a nice sized repair job. Given that the PO seems to have not taken proper care of the vehicle I am seeing $$$$$$ in your future. I hope this turns out not to be the case.
probably true that they will find more stuff, as you do a tear down of the front suspension its easier to see wear on items you couldnt see before, or finding out the new stuff doesnt fit right due to bending thats not obvious
