I am a Porsche-hedger, and in fact offering my advice for free.
Much prefer the looks of the 997, cleaner, sharper and just right.
Otherwise, the guy that said "these cars can't be compared" is on something (sorry). Hope you're not saying the performance of the 991 cannot be compared to the 997 -- because all the 997 has in its favor is its looks, size and hydraulic steering... otherwise the 991 defies physics and has gotten VERY good reviews (even with pdk). You're only argument is that the 991 GT3 wasn't designed to be a manual and therefore will not perform as good as the 997 in that form.
I'll continue... question is:
Will the 991 GT3 RS be offered with a manual also... if not, 997 RSs will be worth $$$.
If so, that leaves us with the 2009 997 Turbo Manual, or the 997.2 Turbo Manual to take the place of the last of a high-end 911 model with a manual and that will be where my money is.
Lastly, there's a funny, fairly uniform mood here in the GT3 section.
The 997 Turbo section, and yes F-Chat are much more inclined to discuss appreciation. Of course you always get some that say "Just enjoy it, it's car," but what if I enjoy appreciating
, drivable assets? Maybe I'm totally delusional, but until the 993 bubbles burst I'm going to maintain that I'm not.
Excuse my aggression.
