Hello municipality, I am facing the decision to buy a roadster. Since it is supposed to be with steel roof, only Z4 2.3 sdrive or SLK 300 remain for me 1. With the SLK fell with the proportions much better than with the Z4 with far too long bonnet. 2. I assume that the SLK after 7 years is a mature car. The SLK is a run-out model, technology etc. compared to the Z4 five years older and the price for a 2009 it starts at about 34,000. The R172 comes next year, I still like the R171 well, inside and outside. Now my question: buy? or would it be unreasonable? I am grateful for all the answers and advice.
