What is the most reliable engine type for a Vauxhall Insignia?

I've heard mixed opinions on the various engine options available for the Vauxhall Insignia. Which one is the most reliable and worth investing in?

Based on my personal experience with my own Vauxhall Insignia, I would recommend going for the turbocharged petrol engine. It has been extremely reliable and has great fuel efficiency. Definitely worth the investment.

I've done a lot of research on this and according to various reviews, the diesel engine seems to be the most reliable for the Vauxhall Insignia. It may be slightly more expensive, but it's definitely worth it in the long run.

I would personally avoid the hybrid engine for the Vauxhall Insignia. It hasn't been on the market for very long and there have been some reported issues with reliability. Stick with the tried and tested options.
