Here is my 2 cents worth...
If you want the V6 you won't go wrong. It has 300+HP and great mileage you will be able to smoke a lot of things out there.. and with an aftermarket that is embracing this car... it can only get faster.
Do not fear buying from GM even in a situation like it is. WORST case ... Chevy would be the only one standing (hightly doubtfull that it would be THAT bad) and you will always be able to service any GM car at any chevy dealer.
Reliable? These cars are designed to take a beating. So I wouldn't worry about that.
And if your social circle is all about imports.. well.. it's fun to be the black sheep! Come to the dark side... you will like it.
