There was a VT thread on here like yesterday, so you might want to check that out.
Otherwise the standard problems with the VT-VX 1 is generally them chewing out rear tyres with their crappy
IRS, so check rear tyre wear. Otherwise it is Powersteering leaks and brake rotor warpage. Interior Rooftrim also used to fall down in Commodore's, pretty sure it was fixed by then, and well its not really a major issue.
If its the first car for a girl it might be best to make sure thae car has
ABS, because im not certain that Commodore Executives got
ABS until VX2.
