I produced the Zenith manual and had the joy of spending quite some time there in the process. The forward thinking, attention to detail, quality control and just about everything else I witnessed was outstanding. But beyond all of that is the fact that if you have a problem they are there for you and sort it out. For example, I had a reduction belt pulley failure last January and when I got home I mentioned it on my Facebook page. Within ten minutes I had a message from the Jim the MD asking what was needed and a complete set of replacement parts, including bolts, arrived free of charge by the next post. There's no messing about, they take customer support very seriously which works for us and for them. You need to remember that this isn't a Ford Focus with a local garage able to fix issues, it's specialised and you need the support of the manufacturer if anything goes wrong. For balance I should mention that other UK manufacturer's also offer good customer support (it's just that I have experienced Parajet's).
