I did a car swap with one of my friends and here what I felt:
Cars: Mine is 2000 Base, 70K, has 18" wheels and 997 shifter
Friends car: 2001 S 55K, has a factory package with PSE (not sure what it includes) 18" wheels
We swapped cars for 2 days, both cars are daily drivers, no performance upgrades.
My impressions:
First day I was impressed! S has more low end torque (under 3k rpm) and is getting speed faster, It's noticeable stiffer which was really nice on Highway ramps, 1st gear is shorter so I didn't have to downshift to 1st when traffic was slowing down to 10mph. (with 5 speed 10mph is about 1.2Krpm which is bad for IMS

)
The not so good:
- S is stiffer and it get's annoying after 1st day especially with "smooth" seattle roads.
- Maybe I'm used to 5 speed but it seems that I had to shift a lot between 2-3-4th gears it's easier with 5 speed
- S still "feels like a porsche" only after 3.5-4K RPMs, and after 4K RPMs base feels just the same (I didn't feel any difference)
- S is speeding faster and I missed that "I'm accelerating" feeling
- PSE is LOUD, and S in general is feeling louder (even tire noise)
- 997 shifter is a MUST!
- starting from a green light is kinda the same unless you rev the engine, which is fun but you cann't do it every time, clutch costs a lot.
- White gauges are very distracting
Again it's my daily driver, I don't track it so after driving S for 2 days I'm over "should've bought ans S" feeling.
My friend paid almost twice the price for his car (mine was 9k, his 17k)
Would I buy an "S" if I had the chance? YES because I'm still young and I want anything faster bigger better... would I pay more then a couple of grands for it.. definetely NO
Funny thing: my friend told me that he hates how stiff his car is after driving my base
Thanks
