I've named all my cars. My Honda is a "she" and is called Tess. I personally do believe cars have personalitys, and used to give her encouraging pats on the dashboard back when she had starting issues, which are now thankfully resolved.
The only one I haven't named is my Lexus. While I appreciate it is a lovely car that is uber reliable, it justs leave me with an emotionless feeling. Maybe I am the only one, but I get the same feeling when driving a VAG, like a Golf (not a dig at you Jamie!) or an A4. Sure, they are pretty reliable and are great for getting you from A-B, but they are just so boring to drive. Excluding the fruity V6's, they sound like washing machines, have steering number than a porn actresses arse and have less character than a brick.
Seems like every car is like it nowadays too. Honda have wiped Type-R's off the map, Fords RS department is out of touch with themselves and Audi is still making cars that love to understeer. Seems like the only guys who are making cars that require some level of driver input to drive fast, is BMW!
