WIfe has Sport one not the R line. Got it on Feb. Really like it. Fully loaded with full leather, sat nav, park assist, parking sensors, reversing camera and heated seats.
only real difference with the R line is the wheels. I would opt one one with as much spec as possible even if it means not the R line. The 175bhp is just a simple chip that needs doing so dont rule out the 140 versions either. Sports models come with 18's a firmer suspension.
