My lovely Wife say's the same, all of our cars have had names but you can't name them until you know them.
So far we have had;
1994 MX6 Mazda - Penelope - Just suited her
1986 XF Falcon - Peter - As in Peter Falconio, kinda sick, kinda funny.
1984 L200 Mitsubishi - Ishy
1989 Mazda 929 - Bear - He was a big brown bear, lol
2000 VR4 Galant - Cassius - Because he was black and packed a punch
2001 MX5 - Mr Fox
1996 Ford Raider - Canyonero
1997 TE Magna - Magnus
2005 Citroen C4 - Plastic - As in french band Plastic Bertrand and C4 plastic explosive
The GC Hardtop doesn't have a name as yet, I guess he is not yet completed so hasn't revieled himself and therefore can not be named.
