Hello, new to the forum. I currently own a 2001 mercedes ml with just over 90k, and as much as I'd like to say I love it, its ride is horrible and it's been giving me a lot of problems lately. I was thinking about trading it in for a 2001 X5 with 115k, and I was wondering if it's worth it. It's been dealer serviced all it's life, and I might be able to pull off a just-about equal trade with the dealer. I hear the X5 is more reliable than my ml, the mileage scares me a bit, but I'd like any thoughts . Thanks!
