Depends on how much you like driving this car. Do the W210 wagons have AIRmatic, or do they have coil springs on all four corners? If it's coil springs, could you do a little DIY?
With coil-spring cars, there's the spring, and there's the shock absorber. Usually, springs are lifetime items unless they crack, but the shock absorbers do need replacement about every 15 years or so, so yours is about due. I'd find out if the springs are cracked--in which case the job is bigger--or if it's just the shock absorbers. Just last year, I replaced the shock absorbers on my truck, using Bilstein shocks, and it wasn't all that difficult. Yep, I also live where they use road salt. Soak it well with some penetrating oil (e. g. Liquid Wrench, WD-40, PB-Blaster, and so on) beforehand. Might also pick up a propane or MAPP gas torch to heat things up before applying the penetrating oil; heat often helps. I use a propane torch, and it helps.
If you can do this, then you'll likely get a lot more miles out of that car. If so, might as well do just that and keep driving it.
