The thing that kills this thing for me the most is that a new Corolla is roomier, more comfortable, much nicer inside, the top model is is as well equipped, arguably has a better looking exterior, drives better, gets far better fuel economy, is built better, costs 1/10 to service, and in five years will be worth about the same despite the original price being half.
The CLA doesn't stack up against Camrys and Accords and Fusions because it doesn't even stack up against Corollas and Civics. If it were $22K and competing in the compact class, it would be an also-ran.
