Here's my opinions, for what it's worth.
Everything is relative. You can't really say that one car is better than the other, it depends on what the user wants to get out of the car.
Personally i think top speed isn't an issue, torque and how the engine delivers this, is the main thing that i would be looking at from the performance side of things.
As far as interior gadgets, air con is just an added bonus to me, not a big buying point. The 6 cd changer is handy, but again, not a deal breaker.
When it comes to looks, i think the 160SRE wins hands down. It's subtle, not boy racer'ish but can still deliver a good performance.
Like i say, everyone is different. These are the points i like about the 160SR (which is why i'm getting one). I got an ex-demo with 2900 miles, with my part-ex, leaving £6000 to pay.
For that money, leaves no descisions to be made.
