It worth spending 800.00 to 1,000.00 on a 95 celica

Tough question, too many variables..... miles, condition.. but it would have to be in decent shape, without oil leaks, running well, then yes it's worth $800 easy. just keep in mind it's 18 years old

geographic location???? in New England regardless of physical appearance, any running vehicle is a minimum of $1000., however you should be asking yourself....****you know your finances**** we can only assist in practical scenarios, and assist in predicting potential problems with vehicles in general, so sure if you can afford it, why not., if you like the car, or a personal favorite, then definitely, any car can disappoint at any time. If you posted pics, it would better assist in our understanding of the car. I know I didn't help, but what would be the life expectancy in your eyes, is it for commuting??? David said too many variables

Question is...... How much will you spend beyond the $800 to $1000 to keep it running. As the other gentlemen said "it's to hard to predict".
