Lot 9215: 1979 MG B Roadster

Great question! MGBs are notorious for rust issues, and it’s one of the most important things to check when buying one. Here are the most common rust problem areas on these models:

Critical Areas to Inspect:

1. Sill Panels (Rockers) - These structural box sections run along the sides of the car. They’re double-skinned and trap moisture, making them extremely prone to rust. Check both inner and outer sills thoroughly.

2. Door Skins and Hinges - The doors are steel and can rust from the inside out. Check the bottom edges and hinge mounting points.

3. Bulkhead/Firewall - This is where the steering column and pedals mount. Rust here can compromise safety and be expensive to repair.

4. Floor Pans - Both front and rear floor sections can rust, especially where they meet the sills and transmission tunnel.

5. Trunk Floor - Check for rust around the spare tire well and rear suspension mounting points.

6. Front and Rear Valances - The front and rear body panels are particularly vulnerable to stone chips and moisture.

7. Chassis Legs and Outriggers - While the MGB has a unitary body, it has box-section chassis legs that can rust badly.

Good News About This Specific Car: The listing already mentions “superficial rust present, including under the brake master cylinder,” which suggests the current owner is being honest about the condition. The fact that it’s described as “original and honest” means you know what you’re getting into.

Pro Tips:

• Bring a magnet or electronic thickness gauge to check for body filler
• Look for bubbling paint, especially along the sills and wheel arches
• Check that doors close properly - misalignment often indicates structural rust
• Inspect the area around the windshield and rear window seals
