Honda.....
You have to love the Small Block Chev, its a great engine, and the Corvette is an awesome car.
Chev also have the best RWD platform, although Ford does have access to the Australian Falcon platform.
However, in the last 10 years GM has gone bust and been bailed out. They have made some very average cars even more average and have developed nothing in terms of new technology.
Ford got themselves in the shit, but got themselves out of it.
They have also developed some totally new 4cyl, V6 and V8 engines in the last 10 years. Engines that make the Chev equivalents looks very dated.
