Went on the classic tour last time they went to Jersey, been to France and isle of man too on the tour.
Jersey is good but it is a small island. Some good ww2 history there if your interested in that sort of thing.They normally go when the motoring festival is on which is really good. They do have a big Ford contingent in Jersey and there are people that religiously go every year wherever it is.
If you enjoy a lot of driving I would wait and do one on mainland Europe, but up to you.
Best tour for me has to be the IOM, going round the tt course👌 even if the engine did blow up😥
