Hello, after reading the forum for a long time and being an enthusiastic Volvo driver, I got a good idea about the convertible here. I bought a C70 convertible built in 2004. It’s a 2 Lt. engine with 163 hp. The exterior color is black, the interior is beige. Normal equipment with seat heating and automatic transmission. BBS rims with 225 rubbers. After reading the information here that the convertible is better with a Domstrebe it was ordered immediately after the purchase at friendly ” expensive “. Domstrebe is installed and see it drives much better. One is in contrast to my V70. The boxes are much better and the convertible is much deeper. Did it then buy a better sound system? If yes, how can I determine it. And can it be that I have a sports vehicle? How can I determine it? Nothing is registered in the letter and bill. MFG Sven
