2008 Toyota Camry buying a car

Those are a little new still to have seen many problems. You will get different opinions based on personal preference.I have owned Chevys and Toyotas, and got great service out of both. I would suggest you drive them and see if YOU liek one better than the others, it will be your car and if you dont like it from the beginning, you likely never will. My opinion, the Camry or Malibu

IF it was me, I would be looking at the camry, given the choices you list.

No matter how many things that I could list about common problems would not mean it would or would not happen. Given the fact that these are relatively new vehicles means the manufacturer may have made design alterations to fix old problems. These are too new too truely track common problems.

I don't like the Hyundai. Getting good info to work on them is lacking and when you need things, it is more common to be stuck having to go through the dealer.....and hope the part is in stock.

The Chevy...
I think the GMs are not made well. I like my customers to won them because I see them more often. Not to say they are all bad...I'm just not impressed with today's GM.
Are you getting the 4 or 6 cylinder?...if you do?

I like the Camry as they tend to go the distance, but the Maintneance really needs to be followed on it...like any car. I have heard of some powertrain management problems with them...but I haven't had any in my shop like that.

This is my advice.
Don't get a brand new one. Get a 2-3 year old car that someone else took the severe depreciation hit with. Be patient and you'll find one. You'll get one with 20,000 miles if you wait.

To find one, Keep an eye out while driving around town, Check E-bay, Craigslist and the paper. Mention to your mechanic about you interest, sometimes a custome dies and the family needs to move the car on or what have you.
