That's a good deal price wise, assuming very good or better condition.
However, I would NOT get a vehicle with the third row seats unless you absolutely need them. Vehicles with 3rd row seats come with runflat tires and NO spare. Runflats are VERY expensive and a bit harsh riding. And if you have a flat in a remote place, you might have an issue finding a replacement. If your E70 has no third row, you get a space saver spare tire in its place, and conventional tires. There are FAR more tire options if you don't need runflats. Also, the third row is suitable for only small kids anyway.
One problem with finding a highly optioned E70 is that many have the 3rd row. There are SO many different options available on an E70, you need to set your priorities. If you want a used E70 with the exact options you would have ordered when new, you could be looking a LONG time. Use the VIN decoder, (
BMW Model Archive · BMW VIN Decoder · bmwarchive.org ) and make absolutely sure the car you are looking at has the options that are really important to you. As an example, there are several different front seats you can get in these cars, with various motorized options on top of that, plus options for heating, cooling and butt massage. I'd bet, all told, there are at least a dozen different options for the front seats alone. Make a list of the thing you must have, and then add the things you'd like. Most likely, you'll have to compromise somewhere, because even finding the right car, it has to be in the right condition at the right price. Some things can be easily added after the fact, (wheels and flares, although not cheap, are easy, adding satellite radio is also easy), some with a moderate degree of difficulty, (heated steering wheel), some damn near impossible to add later, (heads up display, switching from standard to DSP radio, etc.) So get a super clean car that checks your "must have" list, and any other gadget it has will be a plus, and you'll be happy. And a super clean car that has some mechanical issues can always be fixed, and you'll be much happier putting money into a car knowing it's in great condition cosmetically. And with ANY E70, you WILL be spending good money on repairs.
