So Long!

Bootle Bumtrinket and I are soon to part. She is (was) my first car and we had loads of adventures together. The last one resulted in a somewhat injured back (mine) and a smashed bum and rearlights (BB's). BB has been sweet and forgiving and low maintenance. Now, that ze second one is one its way, I am looking for a name. I may get a Swift or one that is slightly bigger.

The names I have shortlisted for the Swift are:
1. Bootle Bumtrinket II (BB II)
2. Giselle Bumchen
3. Black Booty (It's probably going to be black)

The names shortlisted for the other bigger car (Honda City, Indigo, Swing?) are:
1. Priscilla Queen of the Dessert (PQD)
2. Super Bitchin' Motion Car (SBMC)
3. Carly pedalpusher

I need help in choosing the names, please!
