Let me tell you about both cars. I was working at a Chrysler dealership for 2.5 years and now I work for Audi.

I own an 04' SSB M6 Crossfire, so who better to tell you about these cars.

It's my daily driver, so I'm in it a lot. The looks alone are just that, you get looks from everyone all the time. People come up to me and ask what kind of car it is, is it fast, how much does it cost?

CHICK MAGNET, CHICK MAGNET, CHICK MAGNET!!! I'm going through a divorce and this has helped me in more ways than one. I got in April '04 for my birthday when Chrysler was offering for a limited time to employees, "Employee Pricing on all cars". We don't always get the E.P. $1000 out of pocket, $300 a month, 39 months, 12k/yr. I know that's nice, but someone else messed up in my favor. God loves me.

Livevil, I'm not sure where you live, but I live in Northern New Jersey and it snows here. Not a hard weather car with the Michelin, Pilot Sports. I suggest getting a second set of tires for winter, if you live where it snows a lot or getting a Jeep Wrangler like I have.

The 6m is very poor to say the least. I'd almost go against everything I know about driving and get the 5A. I've gone through syncro's and not it pops out of first gear, constantly missing and grinding gears on fast take offs, if you don't watch it. Plus the auto gets better gas mileage.

This is the MOST COMFORTABLE AND BEST HANDLING CAR IN THE SEGMENT as far as TT, BMW, Nissan 350Z, MAZDA RX-8 (which shouldn't be in the class at all), Porsche Boxter, etc...
It might not be the fastest off the line, but once I hit second gear, look out and when they're breaking for the curves, I'm down shifting, coasting through and accelerating out the other end, before they're even in the first half of the curve.

As for the TT or the A4/S4 line that's a different story. I like all the cars in the Audi line. I'm now leaning towards an S4 M6 Quattro, unless I wait for the RS4 for a few months. The Quattro AWD system is World Renound. This system actually makes these cars faster than the competition, that's why they were banned in a lot of race divisions as an unfair advantage. But there is a bit of under steer on them.

X-fire has no spare, so don't get a hole bigger than your finger. The Super Fix A Flat will seal a good sized hole.

Audi gets a spare and all tires are the same size. (AWD Requirements)

X-fire has room for 2, really cool custom luggage and a lot of room behind the seat.
Audi has four doors on A4 and 2 on TT w/ rear seat on the coupe.

Audi has ultra cool paddle shifters, or M6.
Chrysler has auto stick or M6.

If you get the Crossfire, get the Michelin Pilot Sports they're a far superior tire for this car. I had them as the original tires. We got a trade in w/ 3k miles, I needed tires because of a hard hit, bubble. The Continental tires are not as good as the Pilots.

Michelin, Pilots: softer, quieter, smoother, no squealing around corners and harder to break loose/burn out, wear/last longer.
Continental: harder rubber, wear faster, make road noise and harder to balance, squeal all around the same hard corners where Michelins weren't even trying to hold on. You get the drift.

So in conclusion, there are a lot of differences between the two. The choice is ultimately up to you.

Audi has owner loyalty rebates now and the lease on an A4 2.0T Quattro auto or manual is $369.

Chrysler has E.P. Plus, but I don't think the plus is a lot on them. The dealers will go down a little more, but don't beat us up too bad, everyone wants a good deal. Both sides. A lease on that should be around the $345 mark give or take a few $s.

As for the color, Saphire Silver Blue is the best, because it is constantly changing. Please don't put a sunroof in the car if you get the coupe.

Drive them both. Either way, let me know if i can help you. I might be close enough to sell you one. I can still get you a great deal at the Chrysler dealership as well as here at the Audi showroom. Let me know...
