[NoiSeeVT]

I have an 02 SVT and it has been great to answer your questions:

1) Gas, premuim is a must min 91 octane.
2) City Driving 400km per tank but the tank is smaller than average (40L I Believe) Ive gotten just over 500KM Hiway
3) Heat shield falls off dealer will fix easily if under warrenty if not large heater hose clamps can be done at home. Some people have had issue with the clutch but their is a TSB from Ford if the car is still under warrenty (check out svtoa.com for more details.) Im sure others will add some of their personal issues, knock on wood mine has been great but has really low miles.
4) For mods you can do springs exaust, intake TB, a lot is already there, I have left mine alone.

Just a word of warning about waiting on the SVT many are close to the end of their warrenty , as the last year for production was 04, most will be up in 07 or the miles will be up there. Just something to think about and to extend the warrenty to 7 years 150k your looking at $1895 for full coverage and thats only available if you buy the car before the 3/60 is over.

Just some thoughts
