Hi all I been through the forum and seen a few similar posts so sorry if a repeat. I have the 1:64 scale micro set for my kids aged 7 and 12, which is fun but they have outgrown it. Looking to step up to the full size is that 1:32? The micro I felt wasn't great quality etc so want something decent that will last and I can add too. I was also looking second hand and see items like the digital supercars set with the Bugattis. Is this the latest and can I add to this and get new cars, do these have controllers and can I use iPad etc ? It's all a bit confusing any idiots guide ?! Thanks
