No, it's not a fact that every newly designed car has many bugs with them. I have/had 2 '96 GTSs,early #s, first year for Gen II, that I have not had the first problem with.
Yes, it is a fact, as a matter of fact, that EVERY car has many bugs with them. This fact starts with the very first car designed before the start of the past century. Car companies have been in a constant mode of improving cars since day one. Still, there is no such thing as a perfect car, even after DC has had the basic design of the Viper for over 10 years. This also goes for Ford, GM, Honda, etc.
