I have just had Speed Limit Assist retro fitted to my Mercedes E350 by Neil. As ever, he did an excellent job. I have used Neil 3 time previously (2x ipod kits and 1x reversing camera). His work is of the highest standards (equivalent to factory standard in my opinion) and his level of service is excellent. I find his prices are reasonable and I would happily use him again ata some stage in the future.
