Excellent service. Honest guys. Would definitely recommend. — Manny Sandhu from Islington, North London. ( 2nd of February )I called Add Detail after another HIU repair service told me that my unit needed to be replaced because parts were discontinued for my 8 year old unit. This would have cost nearly £4k. I called Justin at Add Detail for a second opinion. He was able to source the parts and fix the unit for a fraction of the cost. Excellent service. Honest guys. Would definitely recommend.
