I have this posted on gpforums as well but thought the more exposure the better.

Im going to be buying a new car.
I have $15,000 cash to spend.
I have set my sights on a Mazda Atenza, nothing else tickles my fancy.

I have found four cars on trademe, all in Auckland so email will be how i correspond with the car yards.

These are the four cars,

The fourth one is the one i want but could go with the second one (don't know if the bumper looks out of place or not). Part of me likes it but part of me thinks there is too much overhang on the sides.

The 4th one's car yard matches and beats prices on similar models and specs so that is on my side to haggle as 3 of the cars are pretty much the same thing.
The 2nd and 4th cars have been on trademe since march so that's also on my side?

Should i be looking at km's or the condition of the vehicle when choosing one?
What would my chances be of getting one of them down to my price or near enough to it?

The '02-'04 models are in my price range but want something newer and thought I'd give this a go first.
Im guessing i only have one shot at the haggle so need to get it right the first time.

How would i go about it?
Any advice or help is appreciated.

Last time i brought a car i was pretty clueless so want to get it right this time. Also the prices etc on Trademe have me stumped as most cars are the same but have very different prices.

Cheers.
