W have all been advised to take things easy today as we are climbing to 4500m. We had a step ascent to the summit and unfortunately it was too much for the car. We made about three quarters of the way but had to be towed to the top by another crew. At the top we were all feeling very shaky and dizzy but as we descended again felt better. The view from the top was certainly worth it. That night we changed the spark plugs and tried to lean the car off in the hopes that she will improve. If you think these posts are rather short it is because we are now at 5200m and typing is making my head spin. Hopefully when we descend a little in the next few days I can add more to each day and also some photos.
