If you’re looking for a luxury-performance convertible or 4-door coupe with a proven track record, the 2018 BMW 6 Series cars deserve consideration. The 6 Series is more reasonably priced than some European competitors, yet despite its age, can still run circles around many of them.
BMW’s 2018 6 Series doesn’t offer anything you can’t find in newer, less expensive BMW 4 Series convertible, Audi S5 or Lexus RC F Sport. Those needing a modicum of rear-seat room won’t find it in the 6 Series Convertible.
