What’s new to buying mino cooper s or works??

hello have read a few entries here. i want to ende august a mini cooer cabrio either as s or as works. on the one hand, is the works (equipment-adjusted it is only 3000) worth its extra value too? whereby I guess yes (completely other engine, suspension, 17″ brake system, small disihn play) and on the other, what equipment details are useful respectively unintentionally e.g. disc heating or sound system I have read a few things. it will be our 3/4t venture so that he is rather only meant to have fun (driving otherwise dilapidated bmw for long distances) a little help would be really awesome. 1000 thanks in advance, thomas
