E46 '01 325XI Touring: rear coil springs?

Just back from the dealer...
Both of my rear coil springs are broken!
Nothing heavier than groceries has ever been hauled in this.
(and, no, I *don't eat that much!)

Before I replace the springs with OEM's, aren't there any other
options to consider?
....haven't seen any on the 'net for a 325XI sport wagon;
maybe I'm just looking in the wrong spot (I hope).

Thx&Rgds...pay
