Over badging your car?

I like both badges but I think your instincts are right on. Both would probably be a bit too much.

It’s your car so do as you like period!

Well sure...but what we like is sometimes defined on how it appears to onlookers and that is completely valid.

When you have one of those moments when you're not sure how something will look, it's always good to ask. Often you can spot the people who aren't brave enough to ask or don't care to ask by their mustard stained (yet super comfortable) sweat pants.

At least they're doing as they like! :D
