Currently and for the last two years I have been DIY, recently due to a mate wanting to buy a hot system I've done the rounds, ionic, concept 2o and Grippa. He went with Concept and on Monday we collected his van, absolutel cracking looking system and Carl & Julie were a great team and left my mate full of confidence that he had chosen the right one. I know I'll get shot down in flames but it really does look so much better to have a tidy system vs DIY, yes no one looks in your van but i imagine its a great feel good factor to go to work with one. If you had to go for it who would you choose bearing in mind after sales service, parts and labour, build etc etc...
