I figured out the chords in this one. Pretty cool chords for a pretty cool song. 
Much more accurate then the other version, this one sounds right.

Tuning is standard, with no capo.

Chords used are as follows:

Am: x 0 2 2 1 0
Am6: x 0 4 2 1 0  (note: before going to C, drop the 2 to 0)
C: x 3 2 0 1 0
Csus4: x 3 3 0 1 0
Dadd4add9: x 5 4 0 3 0
Dm/A: x 0 0 2 3 1
Asus4: x 0 2 2 3 0
C6add2: x 3 0 2 3 0
Cadd9: x 3 2 0 3 0
Gsus2: 3 x 0 2 3 x
E7sus4: 0 2 2 2 3 0
A: x 0 3 3 3 0
D/A: x 0 0 2 3 2
F: 1 3 3 2 x x
G: 3 5 5 4 x x
D: 10 12 12 11 x x

Alright now on with the song!


Am
I wanna be bigger, stronger

Drive a faster car

C             Csus4
To take me anywhere in seconds
C             Dadd4add9     Am
To take me anywhere I wanna go

And drive around a faster car

And drive around my faster car
