        Very good and fun SUV with one "gotcha"

        by Chuck D on 2/4/2026 4:40:51 PM

        The X3 is fun to drive and the 4-cylinder engine coupled with the 8-speed automatic is spunky. All wheel drive system worked very well while driving in recent snowstorm. Averaging 26 MPG combined. No spare tire as standard tires are run-flat. This worked out recently when a bolt went through one tire and I was able to limp home about 15 miles without changing tire. Interior is not plush by any means but obviously put together with care. Standard stereo is OK. Car has heated seats and full sunroof. The "gotcha" is that even when bought used, BMW supplied the "Connected Drive Package" for free for one year. The list I was given: Spotify, Incremental map update - OTA, Real Time Traffic, BMW Online- News and Weather APP, Traffic Camera Information, Alexa in-Car Speech, Stolen Vehicle Recovery, most of which is taken care of via Apple play or Android Auto. What they do not disclose is that the automatic seat and steering wheel pre-heat function is also part of this package, which makes no sense. My BMW dealer has informed me of a number of customers caught by surprise.…

        Excellent SAV & Drives Like A Dream!

        by Keith on 1/1/2026 3:57:01 PM

        If you have the opportunity to buy an X3 M40, get one. Amazing driving experience, superb handling, outstanding pick up. If you do a Stage 1 Tune w/ 93 Octane (~$600), you'll push 425 HP- lightning fast! Luxurious ride when it needs to be, speed monster when you want;)…

        Nice car with issues

        by Disappointed on 6/9/2025 2:57:39 PM

        We love the two front seats and all the bells and whistles. However the back seat is another issue. It is very cramped.…
