Trying out a Hohner rocket amp harmonica in D - playing bar chords on a 4 string in open G (bar starting at 2nd fret )

Bug's one man band..

Spot the deliberate error?

As I was motivatin'
Back in town
I saw a Cadillac sign
Sayin' "No Money Down"
So I eased on my brakes
And I pulled in the drive
Gunned my motor twice
Then I walked inside
Dealer came to me
Said "Trade in you Ford
And I'll put you in a car
That'll eat up the road
Just tell me what you want
And then sign on that line
And I'll have it brought down to you
In a hour's time"

I'm gonna get me a car
And I'll be headed on down the road
Then I won't have to worry
About that broken down, raggedy Ford

Well Mister I want a yellow convertible
Four door de Ville
With a Continental spare
And a wide chrome wheel
I want power steering
And power brakes
I want a powerful motor
With a jet off take
I want air condition
I want automatic heat
And I want a full Murphy bed
In my back seat
I want short wave radio
I want TV and a phone
You know I gotta talk to my baby
When I'm ridin' alone"

Yes I'm gonna get that car
And I'm gonna head on down the road
Yeah, then I won't have to worry
About that broken down, raggedy Ford

I want four carburetors
And two straight exhausts
I'm burnin' aviation fuel
No matter what the cost
I want railroad air horns
And a military spark
And I want a five year guarantee
On everything I got
I want ten dollar deductible
I want twenty dollar notes
I want thirty thousand liability
That's all she wrote

I got me a car
And I'm headed on down the road
No money down
I don't have to worry
About that broken down, raggedy Ford
