The Civic SI is over 4k more than the tC! Please do some more research on your own.
The more money cars are, the less often you see them on the road.
Sounds like performance isnt on your mind at all! Just cross out the SI and RSX.
Just get the tC, its the least expensive of the other 2.
Edit: and also the cheapest to repair in the future. If youre leasing it and not planing to own it, then dont worry about part prices. Factory warrenty covers during your leasing.
