Assumption:
-You're not buying the car, or you're not planning on keeping it long-term and you are willing to compromise on certain features.
My suggestion is:
1. Drop Technology Package - if you're not crazy about the HUD: it looks cool and all, and 4 years down the lane, every sedan might be equipped with it, but it's not all that functional. You can get the NAV as a stand-alone or just make do with a Garmin-style GPS.. Smartphone integration is not too exciting.. You may have your own smartphone, just use a basic AUX cable and enjoy your ipod/iPhone/Android..
2. Drop Premium Package - If you're not crazy about the lumbar support, and don't have a back problem/bad back.. I am crazy about lumbar support, and I am going to keep my car for as long as I can, so I have this package.. I already had leather.. I have lumbar support in my Altima as standard option, so I'm not letting this one go.. I can't drive without lumbar support - I took a rental over the new year eve and the car didn't have lumbar, I was freaking out on my way to and back from Raleigh.. the most uncomfortable drive.. I doubt you would like to pay for the Sat radio.. Comfort Access Keyless entry... umm I'd take it if it were free, but no, I wouldn't pay for it.. not all that moolah!
3. Drop HK - if you're not an audiophile. I am - and I need the best sound quality, I need music all the time.. and I cannot drive for long distances if I don't have good music.. that's it.. so I have HK..
4. Drop Cold Weather Package - if you can live with not having heated steering wheel. I have Cold Weather Package and I am crazy about heated steering wheel. I don't care about rear heating much, might be good for my parents when they come visit me, but it's in the package.. so I got the package.
5. Drop x-Drive - if you have enough place to store 4 wheels when the other 4 are being used, and are comfortable swapping out tires before and after winter season - if you have snow (I am kind of geographically challenged and have no idea how much snow - if any - do you get at your place). And if you drive in a sporty fashion, you might feel your rear fish out a little when making fast lane changes/turns on wet/snowy roads on non-snow tires.. - without x-Drive : this is the only regret of my dear friend has, who owns an E92 RWD .. Not taking this option will also let you keep your sport suspension if you go with Sport or M-Sport line, and lower the ride height - if it matters to you.
6. Drop Auto High Beams - they're cool.. not too great.. but they don't cost much as well..
I would not suggest you to:
1. Drop DHP: I have said it somewhere else, and I have read it numerous times on boards, this option alone gives your car - same 1 car - 4 flavors of driving. If you don't take this option, all that would change with the button on the middle would be your throttle and steering response - not suspension - and the suspension makes a hell lot of difference in driving..
2. Sport line - The name of the line is self-explanatory. If you like sport look, sport feel, take sport line. If you just need a daily driver, and don't care about sport feel (hinting at 4 flavors), then take modern, luxury or no-line based on what line suits you. Sport line also gives you sport suspension, which a lot of people dig.. seriously!
3. Rear-View camera: This is becoming a necessity - with the parking spaces reducing every day and more cars coming onto the streets, with your car being used as daily driver and squeezing into and out of tight parking spots, I think this one is a necessity. You can skip on it, if this is going to be your weekend ride..
4. Leather : Cmon dude, whats a classy sport sedan without leather? - thats my opinion..
All the above are depending on your choice/way of life, as it is you who is ultimately going to drive it. You know the best what you can and what you cannot live without.. You are the best judge.. If you have any questions about what is the use of each feature, feel free to ask.. you'll get everyone's opinions, facts and experiences..
And let us know what you finally order.. :thumbup:
Cheers,
