I hope to provide a little bit of info and tell you a few things to think about when purchasing the VX.
1. only a 5 year 60,000 mile powertrain warranty is transferable from owner to owner. Only the lucky guy or gal, that bought it as the first owner only gets the 120,000 10 year warranty.
My VX has 97,000 miles on, and it is my daily driver. I have to put 1 quart of oil in after about 2,000 miles from oil change to oil change and i get my oil changed every 3,000, and only have started to need to do that this year. I wouldn't follow the 5,000 mile oil change interval that is listed in the owners manual. check ALL fluids at regular intervals, and replace as stated in the manual. My transfer case was shot when i bought mine at 50,000 miles 3 years ago. I had no idea it was bad until i took it to an Isuzu dealer and they checked it on the computer. the only sign i had was that my center consol would get very hot, but i didn't learn that that was a sign until after the replacement. luckily it was under warranty and they replaced it at no charge to me. the transfer case alone was $2,000. i have no idea what it was with labor. wheels are steel with chrome. the crome comes off and your wheel rusts. I had to replace them as well.
I don't seem to have any engine or transmission problems. the transmission kinda clanks into place as you move from setting to setting, but goes through gears pretty easily and smoothly. Look for a 2000, or 2001. 2001 had a better climate control system, and 18 inch wheels... which makes for a limited selection or tires, but stands a little higher off the ground. But you could always get 16 inch wheels and get a wider selection of tires including a tire with more sidewall and not worry as much about "curb rash". I almost replaced mine with 16's but i was told by the tire/wheel dealer not to deviate from the original specs. I'm sure there is someone on this forum that can guide you on wether that's true or not, but i liked the 18's, and went with AR Fuel wheels.
I'll say it. This has been the most expensive car i've ever had to maintain. If you are mechanically inclined it might not be so bad. I have found a great body/auto parts store on-line that has Isuzu parts in stock and at great prices-CARPARTSWHOLESALE.COM. I will admit this as well- I love my VX.
there are other things to consider, and i think other members on this forum will help out with questions you may have. Shocks are something to consider. i think the extremely pricey stock shocks are better than most aftermarkets, including the Rancho's, which i have and hate.
I hope this helps you. I'm sure i'll think of more stuff, but this is a good place to start. Good luck in your search.
