Ok thx.Used a guy recently up in Bolton for the Lotus cortina was about £750 ,remember they have a box rather than a rack ,was quoted roughly the same for a Zed and it’s adjustable but to be fair once it’s set up you won’t need to touch it,had to take it back on Monday as burnt out the unit whilst working on it ,stuck a probe on it testing for earth/live and burnt it out hence return to Bolton charged us £80 to replace which was good after three and half hours fixing it
