While I don't have a strong opin on the car, just wondering if you have plugged in
X3s into BMW's car search tab; most are CPO, (slightly pricier), but some days the
available inventory for X3s/X5s, et al, is surprisingly large. You can limit the "distance",
so you aren't looking at cars in Iowa or, the LeftCoast.
