Would you Lexus or BMW?

[Atone]

I recently purchased a little mountain house and have been going back and forth A LOT. It’s impossible not to be covered in dirt at all times coming and going. My off road truck has been dialed in for such escapades but I’m feeling like I want a city car that stays clean, is fast-ish and easy on maintenance (prob rules out BMW). Def want a coupe and would love a convertible but not an option with Lexus (I think). Was looking at a Lexus RC F or possibly m440i. Any thoughts or input from the car contingency? Looking to keep $ around $50k, low miles and as new as my budget allows for - ideally 2020 or newer
