Purchase advice 997 convertible BJ 2005-2008

Hello friends, I have read and searched the forum posts here for some time now. Unfortunately, n few entries are a few years old and I am partly not sure if all this is still true. I’m playing with the idea that my next car will be a “fun car”. What’s more fun than n 911er? So in the case n 997er from year 2005 – 2008. I’ve been looking at it for a while now. I’d be grateful about your experience, which I have to pay attention to. I want the convertible ho My key data: approx.10.000 – 12500km a year a lot of city traffic Drive to work 7km through the city. (along the ring) I want to drive the car as a “daily driver”. That means it will be my only car. I am currently looking at BJ 2005-2008 to max. 100.000km and there we lie between 42T€-54T€. Depending on the KM and the year of construction. Is there a KM limit, where it starts “so slow” with the “diseases”? Will the warm in the 7km? My BMW 635D is getting warm at the moment, for that the route lasts. So oil. I want to drive the car as a “daily driver”. That means it will be my only car. I now have 100€ insurance + tax per month (35% and 500€ SB at VK) and 250€ per month for maintenance + tyres and other jokes. Does this happen with the KM performance per year? Will only have a bit of an overview. How vulnerable is the 997er? unfortunately I can find nothing at all. Many thanks in advance for your experience in advance. Greeting narrow
