Learn how you too can maintain your vehicle and save money. This week’s topic talks about catalytic converters. What’s that, you say? Caddi-lit-ic…is this a General Motors invention?

One of our listeners emailed me at firstname.lastname@example.org and asked why this part is soooo expensive and what she could have done to maintain it — simple answers with simple solutions for you.
