This is also a topic I fitz with constantly. First I just wanna say Keith go drive a water cooled 911, since you haven't already. They are great driving cars inspite of the weight distribution. Make sure your front tires are correctly inflated. Yes, factory inflation on mid and rear engined Porsche's is lower than you expect. That does a lot to help the understeer. I've never had a tire shop set them correctly.
Okay I'm going to hit the big 50 in 15 months, and I'm seriously thinking what do I want for my 3rd car. I really want something that meets all of the ideas posted here that I can drive well into retirement. I'm so obsessed with the idea, I made a spreadsheet to evaluate potential rides (I have a spreadsheet for everything including my magic $# to retire). I graded cars on weight (high weight is bad no matter what anyone says), 0-60, 1/4 mile ET, skid pad gs, handling (perceived), cost, cool factor, maintenance cost, old or new (new being generally more reliable and easier to drive further), coolness, etc. I don't recall everything but I can share the spreadsheet / decision matrix with the group if desired.
The cars I scored: FD RX-7 (always wanted one), C7 Z51 7 speed (going to seem uber cool soon), C8 Vette (guessed on a lot of parameters), ND Miata (going to have to have a Club with Recaros), Cayman 987S, Cayman or Boxster GTS (15/16), Mustang GT with supercharger (Lebanon), GT350, and older Boss 302. To my surprise none of the Mustangs was in the running largely due to weight. I simply ranked the cars 1 to 8 for these kinds of categories. The top 4 where the C7 Z51, C8, 987 Cayman S, and ND Miata (not in that order).
As an aside I then added an LS1 NA to the mix (I have an NA I can sell or convert), and an ND with a supercharger (can't find a 1/4 mile ET anywhere). They both score in the middle of 1-4.
I'm tempted to add a Focus RS to the mix too, and maybe a supercharged twin, but I don't think I'd really like either. I know the 996/997 turbo will just cost too much to own and they weigh a lot more than a Cayman S, and a N/A flat six sounds OMG way better. Maybe I should add sound? I generally rank things like this fair, good, great, awesome. I wouldn't own a car that sounds bad. Handling and coolness were rated the same way.
So this thread is great. I can use it to help me decide how to blow next years bonus for my birthday! Even with a hefty down payment I'd end up financing part of a C8 or a 15/16 GTS, so they may just drop off the list. Surprisingly to me the FD did not score well. It's just a lot of maintenance, pretty unreliable, but oh so sexy and cool.... I may still get one. I'm probably going to drive my top 5 more than once.
I wonder who has a supercharged ND nearby or an LS1 NA they will let me mess around with...... a lot of the other contenders I can just drive at a dealer.
