Welcome. I have a diesel manual SE on an 06 and, having had a 3.0 petrol auto I'd recommend the diesel. Mines an SE with nav, memory seats parking sensors and 17in wheels and that's about it really. Others will have Bluetooth, voice and cd changer but all this is easily retro fitted. My advice is find the best spec best car you can find, each will be different. Try a manual and an auto and make your own mind up. The manual is better on fuel if that's important. Later, 08 cars are sometimes XS spec which is a bodykit, bigger wheels and possibly all the toys.
