Members should be aware that hybridrepairservice,co.uk/ has previously objected to less that favourable comments on this forum, and some comments were removed.
As a consequence, any future negative reviews will also be removed as this forum is in the public domain.
Notwithstanding that, there have been many favourable reports about the effectivity of services provided.
However, it is true to say that true 'experts' in the maintenance/repair of hybrid vehicle battery systems are few and hard to find.
Imho, the Exeter facility is well worth an enquiry, but he is very busy, at times, as Hybrid the version of the Alphard / Vellfire becomes ever more popular.
