Thinking about purchase

[motordavid]

The 2007 was the first MY for the E70; many here would caution the typical first year glitches and gremlins, fwiw.

There are a litany of items that can/do go wrong, potentially...not that all may or will happen to any particular car.

Since the 'info' on 'your' car you is so vague, eg miles, options, etc., it is difficult to be more specific.

Service history, (at least the work done by a BMW dlr), should be available via the seller 'running' his key at the dlr, a price ballpark,
and a PPI inspection by a good BMW Indie are all things I would want to know, before getting too far down the interest level street.

Use Search Tab here, on any page, mid upper right side, third tab from right, and do some noodling and reading, imo.

Xs are great cars, decent in snow with good snow tires, and remarkable handling for its size and weight; they are not easy/fun/cheap to repair, post-warranty.
