Naming cars isn't a bad thing, but there has to be a good reason for it. It shouldn't just be "I named my car Maybelle!"
I've had a friend that loves naming his cars, but they earn the name.
He had a gold 1988 Mercury Tracer that someone said sounded like two Hamsters running around in their wheels as fast as they could, and probably made as much power, so it became the Hamstermobile. It ran for 20 years and 300,000 miles, taught 6 people to drive stick, and I can't remember a single time it ever needed major repairs. It was powered by twin hamsters, it had so much power.
He had a 1994 Jeep Cherokee that did an 1,800 mile road trip while so overloaded the rear diff was heating up and leaking oil. Half the trip was into the New York City area, through valleys and insane morning traffic. The other half was climbing back out again with a car on the back of a trailer, and we had to stop ever hour to let the thing cool off. We didn't have more than $40 in our pocket, and maxed out credit cards. Somehow the Jeep survived. This Cherokee has been stolen and had the ignition ripped out, driven through one and a half foot deep pot holes down logging roads that popped the radiator and it kept running with nothing more than a bottle of water we happened to have in the thing, and it has been driven two miles down a snow covered dirt road with both front shock struts blown out and the tie rods snapped after driving over a hidden downed tree at about 45 mph. That Jeep earned the name "Super Trooper" and it's still running strong. It will never die.
He had a 1988 Mazda 323 GTX that he spent maybe $25,000 on, shipped a motor in from Japan, had an ECU programmed by a local tuner, etc etc. It was a 400+ hp monster that only ran when it wanted to. It was always something. Cracked a transfer case, broke the oil pan bottoming out on a dirt road, blew some rubber hoses for the brakes while driving, had the tranny linkage fail so he had to drive it to the shop with only third gear available, popped a radiator and had to fabricate one because he couldn't find a spare anywhere... it seemed like for 5 years of ownership he got maybe 6 months of street worthiness out of it. We called that one the Angry b****, because it only worked when it wanted to. God damn that car was high maintenance.
If my car ever gets a name, it's going to damn well earn it, and it will be a very special moment in my ownership of this vehicle.
