I think its more coincidence than anything, but since getting my SRT-6 just a month ago, the following cars have popped up in front of my neighbor's houses;
- Porche 911 (non-turbo)
- Honda S2000
- Nissan 350Z Coupe
- Infiniti G35 Coupe

All appeared within the last month. Now, I either touched off an upgrade trend or the 5 of us just happened to be in the market for sports cars at the exact same time. The best part is that I can smoke them all without breaking a sweat
