I bought my ‘nearly’ dream car ‘, but 4 seats it is unfortunately not – there was never in silver met. and light grey leather. Now there is a rear 4 seater upholstery set that would fit for limp 180€ – there I become of course weak – has this ever been converted – the whole middle armrest part ? is the plug and play or deadly ? especially since I do not know if I get the ‘geile’ middle armrests system at all times; equipment I have the suitable base with 4 zones and ventilated rear seats. Are there experiences here ? Greeting Jürgen
