I drive a New Beetle.
Large, insane spaniel = does not get to ride in the New Beetle.
(see above ) = rides in the curatorial spouse's 1996 Jeep Cherokee. Now that's a good insane spaniel car.
What other cars are good for doggy transport? Are you actually thinking about that? Don't. DogCars has done it for you.
Nissan Murano? Feh. Not any good for hauling a dog of heft.
Volvo XC90? 5 paws, my roadrunners.
