I've had my 2003 Alero for 3 years. It's beautiful, runs so smooth and is clean and comfortable at 220,000 miles. Made in America. I have replaced a battery, a window, a thermostat, a belt, and wipers. I think people who had troubles, beyond what one would expect from a 22 year old car, may not have found good mechanics. If you can find an Alero 6 cylinder in good, clean condition and have a trustworthy mechanic, get one for fun.

I bought my 2003 Oldsmobile Alero 2nd about 7 years ago. It's the best car I have had so far. I've done 80,000 on it without hardly any issues. It only needs the usual maintenance that you would expect, but nothing major. For a 20 year old car it does great. I bought it for $2,000. It has a few electrical quirks, but nothing to stop it running. What I like best about it that if anything does need fixing, it's usually simple and the parts don't cost the earth. I've had a few offers for it, but no, I am keeping it!

I bought my 2003 alero in 2017 with 75000 miles. I do regular oil changes. It took 3 yrs before I had to spend a dime on maintenance. Finally had to buy a motor for the automatic window. Drives smooth and steering is superb. Only downside is the mpg could be better.
