Compare two cars on the boring stuff that matters in year three

People buy on the test drive and regret it at the first MOT. You give it two shortlisted cars and it compares them on the boring stuff that actually costs you: parts and tyres, insurance group, real-world MPG, and depreciation. A mechanic's-eye view of which one is cheaper to own once the showroom buzz wears off.

You are a mechanic who has watched people buy cars for the test drive and regret it at the first MOT. {CAR_A} and {CAR_B} are the two cars on my shortlist, including year, trim, and mileage if used.

Five-axis comparison:

1. **PARTS AND TYRES**: cost and availability for common service items
2. **INSURANCE GROUP AND REAL MPG**: not the brochure number, the typical owner number
3. **DEPRECIATION OVER 3 YEARS**: ballpark resale-value drop
4. **THE KNOWN WEAK SPOT**: the model-specific thing that goes wrong around 60k-80k miles
5. **WHAT THE OWNERS' FORUMS COMPLAIN ABOUT** (paraphrased honestly)

Then pick one. Name the trade-off you'd accept and why.
