Father Dean's M5, mom DonnaRae's 528e and son Austin's 535is were, remarkably, all purchased for under $10,000, after the family made a maximum-price rule for its cars. The E28 obsession all started innocently enough, with Dean's M5. Shortly after that, DonnaRae snapped up the 535is. When it came time to buy a car, his parents told him he'd need to get a job and make the purchase on his own. He agreed, under one condition – that he was able to buy his mom's 535is. Once the deal was said and done, DonnaRae found she'd acquired the E28 bug, and promptly bought herself the 528e.
