Used BMW 535 Gran Turismo for sale under $30,000 near me

We've had this car for 2 years and put 20K miles on it. We're the 3rd owner and it's driven mostly by my wife. Bottom line, we love the car. It's a confident ride, even in incremental weather with xDrive. My Hendrick BMW advisor told me it was built on a 7 Series Chasis. It's huge inside with reclining back seats! The double rear hatch design is unique but we rarely open the lower hatch so I'm not sure why it was engineered that way. I'm in my early 50's and this is our 6th BMW. I'd say my 2000 BMW 735i with staggered M Wheels was my favorite but now that we have a large family, this serves us well. Costco trips are a breeze and the panoramic roof is wonderful...until it broke. If you don't have the means to deal with repair costs, buy a Honda. I say this sincerely. We bought it for $19,500 cash from a private owner. At that time, dealerships were asking just under $25K. In 2 years, we've purchased run-flat tires, AC blower motor and Final Stage Unit (bought the parts from Bav Auto and installed them myself), Spark Plugs (they have to be BMW - installed myself), air struts died in the rear (BMW specialist shop), various suspension components (BMW specialty shop), battery, and just last week the sunshade ripped apart on it's tracks. We've spent about $6,000 in repairs (I'm including the quote on the panoramic sunroof and left out the cost of the tires). I'm not shocked because my previous two 5 Series BMW's had issues. Only my old 1986 325 never gave me issues for four years. I do love this car but it's costly to maintain. Now with 85K miles I'm sure we'll see more surprises, but my wife insists on keeping it. Personally I'd rather see her in a Lexus GS 350 AWD but she says the Lexus is dull. BTW - on two occasions the engine completely shut down on her and left her stranded. We took it to the BMW dealers and they found no issues. I don't feel she'd have this in a Lexus.
