Buying a new car... need your suggestions/inputs

I'm planning on getting a car really soon. After researching since summer of '08, I've narrowed by selection down quite a bit... Here are my few choices in no specific order. Which would you suggest? Reliability is the most important; next, the lower the maintenance the better; and sportiness/luxury is on the same level of importance as maintenance requirements.

Each of the cars is unique in its own way. While one may be more sporty, the others may be more durable. And there are things I love and hate about each and every one of those.

Other suggestions are welcome too.

My current thoughts...
Nissan 350Z: Most reliable for the amount of effort/money needed to be spent on in comparison to the other cars. Many people don't like the looks of the Z, I'm still debating. And this car has a timing belt, which costs quite a bit to replace every once in a while.

Chrysler Crossfire: American = no reliability. That's the general consensus almost everyone can agree one. But, it uses the MB's SLK engine, which makes the reliability issues a little better. I hate the look of the hatchback, but love the convertible. Maintenance/repair is lower in comparison to other cars.

Cadillac CTS: The safest car in the selection, also the least sporty. The handling on the CTS (or at least the CTS-V) is similar to European cars because most parts of the performance parts (other than the engine) is similar to German cars'.

Audi TT: A bit feminine looking, but the convertible is a bit more masculine. The maintenance is ridiculous as I know some people with Audi's and when they talk about their car, complaints about maintenance comes up every time. But when the money is put in, the car should be able to be counted on.

Mini Cooper: I hate the interior design of this car. But you can drop $150 for an extra 50HP. Maintenance is almost as bad as Audi, but a bit more reliable.

Japanese cars have tons of electrical problems which are very expensive to repair.Most Japanese engines are interferance engines and will bend valves if a timing belt break not caught in time.The Crossfire has that POS 2.7 which is a huge piece of junk.Chrysler is still having problems with the 2.7s.Cadillacs are expensive to repair and there is one thing about Cadillac: There is GM and there is Cadillac,Cadillac does it their way.The foriegn car makers need to keep their profits here,not to Japan,Germany,Sweden and Korea.Plus the Japnese take the retirement money to Japan also.
