Purchase decision Mini Cooper S

Hi, I’m new here and I have a very “remarkable” question right now. Drive a Polo 1.4 TDI, where there are many repairs at the moment. Now I got an offer from a friend (BMW & Mini dealer) for a leasing withdrawal. Mini Cooper S, 36,500 km, EZ 05.07 Dark Silver Metallic, fabric/leather combination ray cream white -elek. Glass roof, xenon, climate control, seat heating, mini boost CD, multifunctional steering wheel, Chrome-Line interior, rain sensor, BC, piano black Painting inside, LM-Crone … (I unfortunately forgot 🙂 are painted if desired in car color and get new tires (since the previous owner gets a new Mini JCW and are currently mounted winter bikes.) Price 21.000 € I have no experience with Mini, and the search at mobile also did not yield anything suitable. Is this price ok??? Have reserved the car until Monday and wanted to get an opinion before. Test drive was really great, got me a little into the kl Maybe you can help me a little… 🙂 Edit: I’m a little bit stuck by the seller’s statement, the mini is very stable in value. I haven’t had any experience with Mini before, be it in person or in the circle of friends. With my friends / acquaintances he’s called “gay porsche”. So I can’t expect any help from the side! ;-))
