fix(pl24): cleaner BMW model — append chassis only, drop redundant line token

"Seri" is "{line} {chassis} [{variant}]" and the trim already implies the line
("520i"→5, "X3 sDrive20i"→X3), so append only the chassis(+variant): "520i G30",
"X3 sDrive20i G01" (was "520i 5 G30" / the redundant "X3 sDrive20i X3 G01").
