My Cobalt 4dr SS has 101,000 miles, and still going strong! What a surprise. I really wanted a Toyota, but bought this one for much less. Glad I did. I've spent less in repairs/maintenance than any car I've ever owned. I've owned 3 VW's, 3 Honda's, 5 GM vehicles, 2 Chryler products, and 3 Ford products. This has turned out to be the most reliable car I've owned (in the first 100K miles). Let's see what the next 100k does.
Handling, especially in the mountains All-season tires preferred over simple high speed rated if you drive in snow. Pioneer sound system. Ceiling height. I can sit straight up in this small car. Fuel economy 31 at very lowest, 41 at the highest (driving between 55 & 65 w/o speed changes).
Improve interior materials. Improve plastic connector from fenders to tirewalls. Don't run under 87 octane fuel!!!! It doesn't like it. 88 or higher is best.
