Even in excellent condition, presuming it has air conditioning and automatic, a '93 Protege with 90K mies isn't worth much more than $1,000 as a whole on the best of days. Since any "parts lists" would only provide prices for new replacement parts, your best best would be to use a combination of searches via eBay, craigslist, and any other sources where used vehicle parts may be sold that you can find at least a reasonable comparison and some historical sales data. Best of luck. I hope this helps.
