92 Isuzu Rodeo. Bought as a beater for $800. Put 5,000 miles on it, it stranded me twice, dumped about $1800 into it, and sold it for $600. Lost almost $2000 on that one, not to mention my time being stranded.
It was a fun little truck, just not reliable enough. Especially considering how few miles I put on it. But what do I expect for an $800 beater?
Now I'm worried my '92 4Runner is going to put me in the same situation. I bought it for $2200, have put about $1800 into it, and it still has a few issues. At least it hasn't stranded me yet.
