"Tweety" because it's small and yellow like the cartoon bird.
I bought it in 2006 from the first owner when it was 24 months old with 24,000 miles on it for $6,000 (brown paper bag filled with twenty dollar bills). As of 2023, it has 174,000 and has been a very low cost of ownership vehicle; very reliable but not without it's issues.
I was happy with the factory AM/FM radio until it died. Now I am on my second "cheapest way out" radio purchased online.
