2005 Toyota Tacoma - estimating lifespan

Here, in southern Arizona, it is very common to see the 1995-2000 Tacoma with well over 200,000 miles selling for $5-6k, and it’s even more common to see the 2001-2008 generation for sale with over 200,000 miles, and people are still asking $7-10k for them! I would say that with reasonable maintenance, you can expect at least 200,000 miles out of yours, unless of course the body rusts out before that.
