One thing. Make sure you check the axle seals for tranny oil leakage before you make your journey home. You mentioned the half shafts were just replaced - probably because of split CV boots huh?
Putting the axles back into the differential can be tricky, so as long as a reliable mechanic put them back in you should be okay. But if someone less skilled had trouble inserting them again -LOOK OUT! You will be able to tell if the axle seals are leaking by looking at the underbody frame behind the tranny after running at highway speed. A small leak is not going to be a big deal. If, however, any oil drips down to the ground and forms an oil spot after 5 minutes or so standing still, that indicates the axle seal is torn or has a broken spring. You could run low on tranny oil fast if that's the case.
You have probably bought the best car for the $$$$ you ever will. Heck, your VX might make it to 2020 without too much trouble.
Congrats! Very nice looking VX. And definitely worth every penny considering the fact that it appears to be rust free and has low miles (as low as you could wish for really). Quite some VX's around here already and it seems more are coming every month. Make sure you make a garage entry when you have the car and tell us how you did driving it back.
