Buy New vs Used — Decision Guide

A decision flow, not a calculator. Weighs budget, ownership horizon, reliability needs, warranty value, and depreciation sensitivity to recommend New / Certified Pre-Owned / Used. No fake TCO numbers — this is structured judgment.

What are you buying?

How tight is your budget?

How long will you keep this item?

How critical is reliability? If this breaks, how painful is it?

How much do you value a manufacturer warranty?

Are you bothered by losing 15–30% of value in the first year (new-purchase depreciation)?

Limitations: This is a judgment aid, not a price comparison. Actual total cost of ownership depends on specific models, local prices, maintenance reality, and your negotiation skill. Do NOT use it as a purchase decision by itself.

What to do next: Treat the recommendation as a starting point. After running this, get three price quotes (new, CPO, used) for the specific item you're considering and compare against the watchouts listed in the output.
