Will my car make it through a 8 hour road trip?

i have a 1993 toyota celica with 106k on it (have never had a prob with it sense i got some electrical work done to it roughly a year ago) the longest it has eer been drivin is prob 2 hours one way. (in the last two years that i have owned it) there is nothing wrong with it as far as i know... it has neer let me down. any way what are some tips i can use to make sure my car is ready for an 8 hour trip? should it make it there and back ok?
