Some very strange answers: Yes, the Avensis is a very well built, very reliable car. It won't 'excite' many people, but as decent family transport it's one of the best. Some Japanese parts are expensive, but actually no more expensive than any other Ford or Vauxhall - and being a Toyota, it will need repairs & replacements far less often than most other cars.
I assume you won't be having hand crafted, purpose built cages fitted for dogs, so that shouldn't be an issue.
