Just for the record - Scotty slammed GM products all the time. Research his thoughts on Honda's GDI systems, & you will find he does't think much of them. If you don't drive a Celica, Matrix, or Lexus (three cars parked in his driveway), you probably own an inferior product.
Scotty knows a lot about cars, but his opinion of things can be off. I would never take him that seriously, but I enjoy him just the same!
