I would check : http://www.vehicross.info/forums/sho...&highlight=tsb to see a list of the TSBs so that you can read through what is common and not to worry about.

Then: CarFax Report

Then I would keep in mind the common things that have an easy solution:
Window problem (SBC Bracket) fixes. Not usually an "If", but a "When"
Squeaky over bumps is just inexpensive sway bar bushings, not shocks.
Most rattles can be explained back to something loose.

Then I would check the following items to make sure they are up to snuff:
Belts - Last changed (by whom)
tires - tread left - tire wear (alignment)
fluids - Last changed, with what
gauges - operating properly (Gas guages on several VXs tend to float)
Engine cleanliness (oil leaks, etc)
Check floor where stored for puddles, etc
suspension
exhaust
overall undercarriage
windows operate (motor, not tilt)
hood latch
door locks
head lights
interior condition
seats work (adjust, etc)
windshield wipers
radio
overal paint quality (scratches, sun damage, dents, dings, etc)
Listen to the engine for noises.

From there, I would check the oil level and determine if that VX has a serious oil comsuming problem, or just a minor one. (Almost) All of us have some oil comsumption. Some is 1 quart every 7,000 miles, some is 1 quart every 250 miles. You want the first.

Ask lots of questions and dont pick the first one you see/drive just because you fall in love with the idea.

Hope that helps.
