Understanding the Issues:
* Catalytic Converter: This is a vital emissions control component. If it's failing, your car might be emitting harmful pollutants, leading to potential fines in some areas.
* O2 Sensor: This sensor monitors exhaust gases and feeds information to the engine computer. A faulty sensor can cause poor fuel economy and engine performance issues.
Your Options:
1. Get a Second Opinion:
* Reputable Mechanic: Take your car to a different shop for an inspection. This is a good way to verify the diagnosis and potentially get a more competitive quote.
* Independent Shops: Independent mechanics often have lower labor rates than dealerships.
2. Consider the Cost:
* Weigh the Cost vs. Value: A new catalytic converter and O2 sensor can be expensive, but if the rest of the car is in good condition and you plan to keep it, the investment might be worthwhile.
* Trade-In Value: If the repairs are too costly, the trade-in value of your Metro might be lower, making it difficult to get a decent price for it.
3. Temporary Solutions (Not Recommended):
* Removing the Cat: This is illegal in most areas and harmful to the environment. It will also likely trigger a "check engine" light.
* "Cat Delete" Pipe: This bypasses the catalytic converter and can cause a fail on an emissions test.
4. Delay the Repairs:
* Potential Risks: Driving with a faulty cat can lead to engine damage in the long run. It can also trigger a check engine light, impacting your driving experience.
* Emissions Testing: You'll need a functioning cat to pass emissions testing in many regions.
Recommendations:
* Get a second opinion from a trusted mechanic.
* Discuss the repair costs and your budget with the mechanic.
* Weigh the potential risks of delaying the repairs against the costs of the work.
Additional Considerations:
* Age and Condition: A 2000 Metro with 155k miles is a fairly old car. Consider if other potential problems are likely to arise in the future.
* Cost of Replacement: The price of a new Metro might be less than the cost of repairs.
* Your Driving Habits: How much do you drive and how important is fuel efficiency to you?
Ultimately, the decision is yours. By carefully considering all the factors and weighing the costs and risks, you can make the best decision for your situation.
