Hi, i am now on the look out for my 1st GT86 but weren't to sure on the differences over the years. Am i right in thinking that the 2015+ have redesigned coilpacks that are less likely to fail? if so are they really that delicate on the older models? this wll be my only car so want to make it as reliable as possible, well before the mods start at least i know about the shark fin aerial and slight interior changes. does the 15plates onwards have revised suspension too or is that just the 17plates?
