Its boxier shape makes room for seven, a useful alternative to five-seat rivals. Mycarcheck.com records 945 checks covering 497 distinct VINs, a substantial sample for this exact GLB220 version. The average private-sale valuation was £30,300, while checked cars averaged 34,000 miles and 9,000 miles a year.
