Iso Grifo IR8 (1972-74)

The Iso Grifo IR8, like many classic cars, has a few common faults that owners and enthusiasts should be aware of:

1. **Rust**: The Iso Grifo IR8 is prone to rust, particularly around the suspension pick-up points and behind the sills. It's crucial to check these areas thoroughly.
2. **Electrical Issues**: The electrical systems can cause problems due to age and wear. Wiring and connections may need to be inspected and possibly replaced - Auto Express](https://www.autoexpress.co.uk/classic-cars/105002/iso-grifo-buying-guide-and-review-1965-1974).
3. **Suspension Wear**: While the suspension components are generally long-lasting, rubber bushes can wear or crack over time - Auto Express](https://www.autoexpress.co.uk/classic-cars/105002/iso-grifo-buying-guide-and-review-1965-1974).
4. **Engine and Transmission**: The Chevrolet V8 engines used in the Grifo are robust, but they require regular maintenance. The ZF gearbox, although reliable, can feel ponderous by modern standards.

Regular maintenance and careful inspection can help mitigate these issues and keep the Iso Grifo IR8 in good running condition.
