It was just a general question and I thought it would be appropriate to ask because I was curious. This was not about as to which generation is better, I already stated that I have seen (or heard) several of the Gen 5 Camry beep in that same pattern.
Could it possibly have to do with the enhanced VIP security system that was installed in the car? Because I know I do not have that in mine.
And for the record, it shouldn't matter as to which generation is better. The fact is that a Camry is a Camry, no matter what generation or body style. They have been the best selling and longest lasting cars in America for over 10 years, and I am damn proud to own one.
