Not that it's beat. It has about 63,000 miles on it and runs well. Under the hood is the 3.1-L V6 and autmatic transmission. The paint is crap - damn clear-coat that doesn't stick - and the interior is a little stained here and there (coffee?). The dash, especially over the passenger side air bag, has severe sun damage (I'll buy a dash mat sometime). Right now the A/C doesn't work. Hopefully it just needs recharging and winter is coming. That's about it for the negatives.
On the plus side it's got new tires and a new battery. I just checked the fuel economy and it is pretty good - almost 26 mpg for mixed driving. Not bad for a larger 4-door sedan.
So far I'm happy with the Lumina. It's nothing special but it does its job. That's all you can ask of a beater.
