I had the same issue with my 4Runner a couple months ago. The only differences were that mine was 98 and I only had 83K on the odometer. Oh, and my rust was much, much worse than that. I was able to sell mine for $1250.
Here were my thoughts then, and they're pretty much the same as now:
"The guy on the phone said this probably could have been avoided if I had brought it in to a Toyota dealership for regular maintenance. In hindsight, I guess I should have. I just brought it to local guys for the oil changes and everything else, because it was about half the cost the dealership was charging.
The whole thing sucks, but in the end the responsibility fell on me to take better care of the undercarriage. I've never been a car guy, and only started coming here after shelling out a couple hundred for a brake job 2 years ago and thinking, "I should probably learn how to do this for myself."
Do I think Toyota put a garbage frame on this rig? Yeah, I do. There's fault with the company, but there's equal fault with myself, and if you want to point fingers, I'd probably point them at the Illinois Department of Transportation for salting the heck out of the streets in the winter as well. When I looked at the undercarriage 2 years ago, it was rusted, but not rotted. I hosed it down every chance I got. Last winter, there was only 1 snowfall and the salt was at a minimum, so I wasn't as vigilant. Again, my fault for not keeping up with everything."
Yes, Toyota should stand by its products. But, for how long? My rig was 14 years old. That's 14 years of snowy, salty roads in Illinois beating the hell out of my frame. I wish I'd known back in 2005 (when I bought my rig) what I know now. I would have taken more preventative measures earlier on. But, I didn't know, and so I didn't do what needed to be done. That falls on me. In the end, there's enough equal blame to go around.
If starting a web site brings you peace of mind, good for you. I wish you the best of luck. But, in all honesty, trying to put the entire blame on Toyota doesn't seem like the kind of response people will rally behind. Yeah, it's easy to point fingers at a big corporation, because the little guy is always right. Right?
I hope after you get a little time to find some perspective, you'll be able to move on. Believe me, I don't like losing thousands of dollars on a car either. I wasn't prepared for the situation one bit, and I'm still not where I want to be 4 months later. Soon enough, I'll have moved on completely, and I hope you will as well.
