I have had this car since 2002. It has 250,000 on it now. I purchased it at 176,000. The major problem is the timing belt change every 30,000. I have done 3 so far. I also had to replace the compressor when I purchased it. Recently I had to replace tubing leading to the gas tank because it was leaking gas. Other than that it has been routine maintenance. It is the best car I have ever had. Now I have to add a quart between oil changes which is not bad for a 250K car. I hope I can buy another 960 used with low mileage when this one goes down. I am hoping to make it to 300K.
I have tried and tried to find something wrong with this car and, although it was entirely my fault, i have found only one: the timing belt needs to be changed every 53,000Km, which is fine, assuming your previous owner has done this, however, if it is not replaced and breaks, your valves and cylinders will continue to move out of time, which will send your pistons right into your valves. So far this has cost me 6 months without my 960 (due to financial difficulty) 2 of those it has been worked on. It has only cost me about $1500(US) to replace my head and a few gaskets, its worth it.
