Greetings! I agree with above and would like to add my 2 cents. I have owned my 2 VXs less than 90 days and know a little about cars and Isuzu........
Seems all 99s had red/black interior
Many have mixed opinion about the climate controll....99s simple system-good! less cost to fix_ good-
99s had 16 inch wheels and are less costly to replace tires. 18s on the 2000 and 2001 look cool!
Ironman was a dress up option with decals, floor mats and logo in front seats. Also came with crossbars for roof rack. All were white.

Drive this VX from cold(feel engine) for at least 30 miles and 1/2 hour. Try everything. See if you can deal with no rear window vision, kinda like a van with curtains! See how it shifts when warm and coming to a light. Any clunks or sloppy shifts? Does it run rough cold? does it sound good. Feel good. It should have lots of power and few rattles and noises. Smell it for foul oders under the seats...mice-dogs-kids ect. Make sure jack and handle(2 pc) are in it. Do you have a Isuzu dealer or real mechanic you trust. Ask them if they will work on it? Check windows. still looking for one without window trouble.....
If it passes the road test and all above seems right, and u still like it, I say BUY! remember insurance may be more than what you are used to. Sounds like a good price if all is really excellent as suggested ........Good luck.!! You can find alot of info here...just have to spend time looking!!
