Don't do it. Vanity plates are aptly named. Generally result in auto-deduct of at least 10 IQ points on the 'first impressions scale' (except for DBAG or DOUCHE - you'd score points for self-identifying w/ those, but probably already taken by a certain orange politico for his lambo
). If you want to do a tribute to your daughter, let her decorate part of it (preferably inside, and with stickers that she can change as she changes her mind) or pick a name for it - something a kid would actually appreciate.
And ''no Mercy" - in a 1 series? really? Might add 'Dream On' to the B list.
