I’ve got a Volvo at the moment which came on their approved used scheme with warranty, saved me a lot so far, new partial loom, intercooler, radiator, CCV valve + the labour to fit all at no cost which in my first year was a real benefit.
I would have a chat with a good trusted workshop and see if they know of any good units coming up for replacement. The firm I sub to, also look after my unit and trailers and they have not long got rid of some older stuff which would have done a new starter brilliantly for the first 18 months - 2 years.
