Is it worth buying aToyota Land Cruiser with 185000 miles on it for 8000?

That sure is a loaded question. You will be hard pressed to find a better stock vehicle than most landcruisers. If you are looking at owning a legend then at 185000 you are just getting started. I have owned more than 7 myself. I still own 3 and plan on buying yet another one. While there are some drawbacks like poor mileage you are not buying just another vehicle. I would go for it as long as it shows no signs of rust!
