A soon to be newbie

First off I love this forum! I have learned more in a day reading here then any other single site and even the dealers (which should know more - it IS there day job). Thank you for the help already.

Now for some questions That I could not find, have gotten conflicting info on, or just do not understand what I read.

1. What options are TRULY optional?? I have found before while buying that some "options" are not really optional and you are forced to "buy" since that is what is default on the car. (BTW this really burns me since it is just another level of deception.) I know I have to deal with it so being forewarned is best. . . for example I expect the $260 mats etc "option" is not a option. . .anything else??

2. What IS the difference between getting a III with dealer installed leather and a IV?? Both in items and ball part $$ . . I have gotten allot of conflicting info here. what ARE the after market add-ons possible? I heard that a "normal" sun/moon roof is possible?

3. IS it better to get a III and upgrade it then to just get a IV? reasons? (I really want leather - and I have yet to decide on nav, XM is not needed, ipod/iPhone support is nice though usb or the aux jack is ok)

4. The Nav package I am a bit confused on what exactly it entails and if it is worth getting (opinions).
a. I want Bluetooth, but it is unclear about what that means. (I think "Bluetooth" phone is standred but Bluetooth streaming music is nav only??)
b. Is the ipod controls incompatible with a Ipod touch or phone?? (not clear) . . .and how does the USB connection work?? (just for charging??)
c. Is the nav system + backup cam worth the $$. I know this is quite an opinion charged topic but this also goes with the other questions. (chances are it seems that IVs are hard to find without the Nav etc) a fair functional GPS would be fine as long as it works. if I am going to be fighting it constantly I may opt out . .
d. any other info on this package? as allot of sites say what it is but not in any great detail. (on the of real questions I have with the car)

5. How is the Car in snow, ice, mud, water? Personal experiences? (I have a Scion now and can drive it through just about anything, So I have no need for a SUV ans such)

6. where there any annoying "got-yas" in the buying process? or afterward that forewarning could help others to avoid?

Thanks for any responses!

 

Ok, I know some of these questions where asked here but really I am looking for clarifications as the answer was not plain or possibly hidden in a long thread. (I have found a few "better" answers looking today . . but it is quite slow going . . .
3rd party Nav systems are looking . . good . . (heck did not even know they made them) any experience there??

 

Good info thanks.

"The Prius should not be driven through deep water (as should any car)."
Sure but the term deep is rather relative. I am talking about hydroplaning and large puddles.

Clearance is understandable . . I know this is not a off roader or a SUV . . . but then again like I said I have a Scion now and current quite pleased with it's winter performance (no traction, ABS, or stability control and not much clearance) . . if it is the same or better then the Scion all the better, if not I would like to know the diff if possible.

Can anyone give links on good winter tires??? (that you like) that would be helpful also.

Thanks
