I have no affiliation or association with Kool Classics but they very recently serviced my 2013 Triton 430. They are based in East Sussex and much closer to me than AL which I have used in the past. I thought I would pass on my experience to other owners that might consider using them.
My experience was very positive and I was very happy with the work that they did. They did all of the basics very well and I got a more detailed report on their work and findings than I have with other companies. They also sent some pictures to me as they were carrying out the service and these were very useful. Old parts that were replaced were shown to me. They also sorted some minor niggly issues and gave some good advice in general.
Based on my experience, I am very happy to recommend them for servicing.
