I’m sure that is the case, in terms of 10’s, but they outta be running those times stock at that price. My ST was low $30’s with 15k miles, and it will keep pretty good pace with the over 600 Stock hp X5M just adding the tune and bolt ons.
You must have gotten the deal of a lifetime on your ST for that price.
Few differences:
X3M - No third row, but is only a few hundred pounds lighter than an ST. Non-comp version is 70K, not much more than the ST new for new, and runs low 12's, high 11's stock.
X5M - Weighs over 800 pounds more than the ST, the non-comp version is 40K more than the ST, and is a true luxury car with air suspension and other features.
Tune only, both the X3M and X5M make over 600HP.
The M Package versions also run pretty quick and are much more affordable.
