Keep with them if you can...
I understand that option for tires are getting scarce nowadays...
BBS wheels have been making a comeback the past several years, which vintage versions of BBS wheels commanding stupid prices!
We're talking $2,000 - $3,000 for a set of 15" wheels!
For some reason, the Honda crowd goes bonkers over them, and they are paying premium prices for their 4x100 bolt pattern - which is the same as older BMW fitment.
The only reason to change wheels is because you want bigger brakes which necessitates going up in diameter...
If I could get away with 15's, I'd rock those wheels!
Unfortunately, my big brakes need at least 17's!
