Help on decision. M5 F10 or 430 gran coupe

[Splatter00]

So ive owned 2 f10 m5’s in the past but only for a year each.
Im looking for a new work car and a camry or prius isnt going to do it for me.
Found a 2014 fully loaded f10 with 87k miles asking 33k
Concern is reliability, not really worried about mpg.
Second option is 2017 430i gran coupe with 77k miles for 21k
Meets more of the practical bucket.

My other vehicles are a 23 denali yukon and 23 raptor, so neither would fit as a daily for work.

I drive probable 1k-1.5k miles a week on busy weeks, think a year or teo of use is too much for the m5?

If gas is not a problem then M5 so long as with service history and plenty of oil changes. More room in back with the fold down rear seats.
