CarMax seems so scarf up several BMW Alpina B7 (F01’s) unicorns every year, and this is the eighth one I’ve tracked in the past two years (added links to the other seven at the bottom of this piece). Understand only 500 Alpina B7’s are imported to the US yearly. This XDrive model sold for around $130,000 new, and seven years later is only $37,998.
I’d throw in MaxCare no matter what to shift the risk of repair of this high end vehicle to CarMax. The 2012 B7 is powered by a 4.4 liter, twin-turbo, 500hp V8, a six-speed ZF automatic transmission, and all wheel drive. The car does 0-60 in 4.5 seconds and is limited to 174mph.
It’s reasonably priced for a 2012 with low miles – 9,000 yearly. Here’s a Car and Driver review for a 2011 – there aren’t any good reviews for 2012’s (Reviewers waited for the 2013’s that brought us 540hp, an eight-speed transmission, and removed the top speed limiter, allowing the car to cruise at an amazing 194mph!).  Find this two owner car here in Pompano Beach, Florida. 
Previous Alpina B7’s at CarMax
In September, 2017 I spotted this 2011 B7 in Duarte, California, selling for $39,998 with 43,000 miles.
February, 2018 brought us a nearly identical 2011 B7 model in Los Angeles for $39,998 but with 41,000 miles (yes, had to check the VIN to make sure they weren’t the same!)
And in May, 2018 this 2012 B7, another California car with higher miles at 56,000, sold for a mere $33,998! I predicted a quick sale and it went in a day.
In March of 2019 we saw this 2012 model for sale in Chicago at $40,998 with 49,000 miles (also had a $65k B6 for sale then too!)
Finally, in May of 2019 we saw three B7’s for sale at the same time – a 2012 and two of the higher-horsepower 2014’s, all in the $40-48,000 range.
