don't be fooled! ISF stock tips are built into the bumper, so most upgraded ISF exhausts looks the same as stock unless you can see under the car!

^Yeah I noticed that on a demo car for SEMA a few years ago, not cool.

OP it's two completely different cars, you choose whats best for you.

I would keep the Z and wait a few years as the price of those IS-F's will inevitably keep dropping.

meh, i've always preferred sports cars over luxury cars with beefed up performance. but maybe it's because i'm young xD.

Its a down grade not an upgrade.

Cars get here on big cargo ships

A new 370 here(sport+ touring) its around 47K to 50k. I got mine used (with
3k miles and 5 months of usage for 39,500. I think I can still sell it for 40k, it only has 6k miles.

I saw the is-f today, its in clean condition and I drove it. I have one day to think about it (tomorrow) and decide. The thing is my Z is extra clean (nothing on the paint or wheels). This other car has 25K DD miles (some door dings and scratched wheels) but not bad overall. Its not going to be a easy decision for me.

These are two totally different cars. If you want a four door sedan with a big motor get the lexus. Also has luxury. If you want a sporty two seater thats sexy as hell, keep the Z. You need the back seat, got some youngin's comin soon?

The back seat would be nice for my dog

There ya go!

Anyway, if you miss the Z enough after you get rid of it just get another one later on like me. It's an endless cycle.

Cars are quite the demanding mistress, aren't they?

I wouldn't do it. With a couple mods your z is as fast if not faster than thr is-f. I knew someone who had one and was always trying to get a race going but he never wanted to. What I can day is I was neck and neck with a c63 amg from a roll.

What did you decided?? I've been looking into these also... as a next car when I become a grown up:icon17: I'm in my mid 20's and have no kids yet... But if I had to choose today, my preference would be as follows: 4 door M3, IS-F, Audi RS4, and then the C63.

Anyways good luck with your decision.

All nice cars:tup: Maybe I'll steal your list when I grow up, too! (not sure this is going to happen though...)

Great upgrade you should definetly get that if you can.
Though I'd get a M3 if I were upgrading next.

:eek:
What roll was it?
40 roll?
C63 amg should smoke us.
:stirthepot:

Well guys i have thought about it a LOT, and I think im keeping the Z, the reason being is that i like the is-f but this specific one is not the right deal for me. I have a EXTRA clean Z, its only 1 year old with 6k miles wich I pay 560 a month. To change it for a 2 year old car with 25k DD miles (door dings, scratches, wheel scraches,tires dont match) and pay 700 a month its NOT the right deal. As some of you recommended ill probable get more goodies for my Z and make it faster than a stock is-f.
