Just bought my wife a 2004 4.4 X5 with 98k to replace her aging grand cherokee. I really hope I made an ok choice. I like the vehicle although I feel Audi still builds nicer cars. But since I've owned it the last few months I replaced ride hieight sensor and now have an intermittent starting issue. Also I'm changing the waterpump and accessories since it looks like it is original. I use the recommended castrol oil but I will and have always changed my oil at 3,000 mile intervals even with synthetic. I just don't know how the vehicle was taken care of before. Always a scary thing.
