I salute you guys, an M5 Touring would be the ultimate dream car for me
With that said, I wonder what you mean with this?
"In addition we know that BMW sold the M5 wagon in earlier stages extremely well and stopped production with the E61 M5 in 2010 for unknown reasons."
As far as I remember, BMW sold only appr. 1000 e61 M5:s, while they sold 10 000 e60 M5:s. Hardly a success? Sold well in Germany, but not elsewhere I'm afraid.
