E93 N52 vs N20 F30. Which (if either) 15k car?

Both seem pretty cool for different reasons. I really need black on tan/brown. No beige. Tan. Or. Brown.

I’ll do 1/2 of the work myself. No lift or garage but I can wrench pretty good. Can do plugs, brakes, etc. I think I can do a OFHG. I’ll definitely not be blowing money at the dealership before I’m really sure what the issue is.

E93 - The convertible would be really fun. I love what I read about the n52. Honestly prefer NA because that’s what I’m used to. A little disappointed by the wheels on this one but the interior is dreamyyyy

F30 - The m sport styling is awesome. I also love the tan interior. 4 cylinder doesn’t bother me, but idk anything about N20.

Which would you buy?
