deadtree

Hello all! I bought a 2002 Grand Voyager this month, thanks for letting me join the forum! I am enjoying the car, many foibles and bits I need to fix of course. But the main problem for me is the height of the front end. As you can see from the attached photos, the front is a LOT lower than the back. This is a cosmetic issue (I'm thinking about putting larger wheels on, as the current ones look tiny) – but it's also a functional issue. I.e. crunching front end on speed bumps (very traumatic experience for the driver, as well as the car). Could this be a spring issue that has lost height over time? Or do you think there's something else wrong here? I'd rather have an idea of what I'm dealing with before approaching a mechanic – or if I can do something myself that would be good to know. Thanks everyone for any thoughts on this!
