I have to agree with the "Buick with a 3800" comment.
Used Buicks can be had for peanuts, and the 3800 engine is pretty much bulletproof. It's why they are so cheap in the salvage yards... They frequently outlast the cars they are installed in.
Find one 1997-98 or later. They will come with the Series II 3800. It's a better design. A decent HP increase over the earlier engines, in a more compact package.
Some of them came with 3100s, but they are pretty much underpowered with that engine, and not as reliable.
Insurance should be inexpensive as well. Since Buicks used to be considered "old folks" cars, few of them were driven hard or crashed.
I was going to suggest a G6, too. The later the better.
Mine is a 2010 GT, ex-rental car, purchased three years ago with 41000 miles. Now has 85000 miles and has been quite reliable.
Had to repair a broken wire on the MAF sensor, three tire pressure sensors, and a brake job. Oh... and a battery and battery cable.
I have the 3500 engine, which is what most of them have. Get a 2007 or later. The 3500 was redesigned for 2007, for better performance and economy, due to VVT.
The 2008 and later Malibu is essentially the same car. (The slightly earlier ones are similar, but don't look as nice.)
