I bought my Monte Carlo five years ago; it's been a great car. I've noticed that the people that are giving this car negative reviews are the owners of the Z34, which explains a lot. When I was shopping, I was warned not to buy the Z34 due to its bad reputation. The 3.1 liter engine in the LS is the way to go if you are shopping. My car now has 170,000 miles on it, and I've only replaced the alternator (at 160,000 miles) and had standard maintenance done. That is exceptional for a car 12 years old, and I highly recommend this car, especially if it is your first. Notice that overall, most people's complaints are about minor things, such as the cupholder.
