I' ve driven all the way as far as Poland. Also a few years ago I had this second hand car bussiness with another partner, and we use to drive to Germany and back to buy Mercedes. I'm pretty much used to drive to Paris, Madrid is a six hour travel by car, but the fuel is so expensive now than you think twice before before using your car, even to go as near as Lisbon.
In any case driving in Portugal or Italy, Spain is better now, for those who are not used for our driving stupidity or madness can be quite tricky.
If I want to go to Almeria in Septmeber, I have to start preparing things now nad if ican make it, it will be only for the weekend.
