Back and forth…

Moin people, I saw a C70 convertible the other day and was enthusiastic about the great design (and the 4 “real” seats). I made myself smart with mobile and autoscout and found quite a lot of offers. After I had informed myself a little bit, the following model would be in my choice for me: – fabric cover – year after 2002 – because afterwards there was a light facelift among other things with clear glass headlights and improved cover. QUESTION: Does someone have a tip, which is the best motorization? – I mean, which engine is powerful enough but also reliable. And: Is the manual transmission or the automatic transmission more recommended? – At the moment I tend more to the automatic, which is probably more suited to the relaxed sliding. And lastly not least: Are there “knack points”, to which one has to pay attention? Thank you and many greetings, MOTUS
