Hi guys, I wanted to get some of your opinions. I am seriously thinking of replacing my '05 997S Cab with an '06 4S..Not only am I smitten by that beautiful 144mm wider rear end, but the performance benefits (through cornering, inclement weather) are enticing. Any thoughts/regrets from you C4 owners? I talked with my sales guy, this would cost me about $20-25K USD, as the sales tax on what I paid would be gone, plus depreciation. On the other hand, I would have a one year newer car, and it would be a 4S Cab, optioned just the way I want. Thoughts please guys! Thanks- Gregg
