Calgary drivers Dionne and Darren Dillabaugh and their nine-year-old twins, daughter Avery and son Grayson, spent a week with the RX 350 Black Line Edition. Neither Dionne nor Darren had ever experienced Lexus before, and both were pleasantly surprised. First though, just what is a Black Line Edition? The model has Lexus’s performance F Sport body style, and adds special blacked-out features, including the 20-inch alloy wheels. Inside, the upholstery is a black and white combination strikingly contrasted by blue stitching. Other upgrades include a larger 12.3-inch touch screen, F Sport steering wheel with paddle shifters and front and rear performance dampers. A well-equipped base model RX 350 costs $56,650, and the Black Line Edition adds $8,850 to the price tag. The Dillabaugh’s vehicle, with destination charge but before any taxes, was almost $68,000.
