## Description

Deciding how to acquire a vehicle usually comes down to a messy spreadsheet of down payments, monthly rates, and mileage limits. This MCP moves that math into your AI client. Instead of guessing, you can ask your agent to run the numbers on a specific car or lease deal. 

You can use it to see how much value a car loses over time or to find the total cash outlay for a lease including potential mileage penalties. It handles the heavy lifting of comparing different acquisition models side by side. Whether you are looking at a long-term purchase or a short-term lease, you get a direct comparison of the total financial impact. It's built to handle the variables that actually matter, like residual values and maintenance costs, so you can make a decision based on real numbers rather than gut feeling.

**Prompt:** 
```
Compare buying a $30,000 car with a $5,000 down payment, $400 monthly for 60 months, $2,000 maintenance, and $12,000 residual value against a lease with $3,000 down, $350 monthly for 36 months, $500 maintenance, and 10,000 miles limit (driving 12,000 miles) with a $0.20 per mile penalty.
