I just bought my first prius... a used 2008 with 116K miles. The car appears to be in excellent shape, visually. Here are some questions I have right off the bat and I'm looking for input on what I should actually have done - because I have no service records. 1) Is there anything special about a Prius oil change? I mean, when I show up for the $15 oil change special, is the guy gonna say "Not for a prius!" 2) Does the electric motor require any maintenance? 3) On the back door, there is a cloth-like material that covers the arm rest... and it is ripped... can one be ordered and easily replaced? Thank you for your time. BTW... I don't even know what prius I have... a base or I or II or whatever.
