Hello, the manufacturers offer a lot of special equipment, some useful, some less. Here it is about the ST and a few extras and what you think about it: 1. Recaro seat package 2 Meaningful? Due to partial leather the surcharge just? Am 1,86m, is there the seat extension necessary? 2. Exterior mirror with ambient lighting Meaningful? Is the look different, worse than without? 3. Badger spoiler extra For the time being I would order it with you… You? 4. Sliding roof -Multiweight at the wrong Position -Open window replaces -All switches occupied, no empty place 5. Reserve wheel (emergency wheel) This makes the rear of the case smaller and is only an emergency wheel at the ST anyway? Then I probably don’t get it 6. Bluetooth package Does it work with any BLuetooth mobile phone? Simple mobile phone in the car and Bluetooth on and via steering wheel/center console accept and speak freely? Thanks in advance
