What to look for when buying vx 5.7l auto

[hovo]

Guys I'm looking at buying a 90,000km vx11 wagon with a 5.7l ls1 donk and auto box. Its a berlina so I think it also has a limited slip diff.
What do I need to look out for? How do I check that the bits and pieces are ok. eg I read somewhereelse on this forum to pump the accelerator at a certain speed to see if it jumps out of gear, but that might have been a manual. But you get the picture.
Are there known problems or tell tales to look for?
Thanks
Jim

the berlina had the option of LSD.. so there is the chance that it doesn't have it
