That's weird, the last 5 pics in the ad are of a totally different bus.  ??? Not to mention the pic of the Future liner thrown in there for good measure.

The second line of the description says "(Other bus w/ Eagle murals in bottom photos is GM 4106 for sale seperately)"

I am however interested to see in the pictures of the second bus that it has a wind deflector thingy on the rear of the roof. Does anyone know of a company selling such things? It so happens I am just at the stage of thinking about a design for my new rear cap, and wondered about the wisdom of incorporating some kind of slot or foil to reduce the vacuum drag from the rear end. There are undoubtably large efficiency gains to be made, but I want to see more examples of existing designs for such devices before building something of my own.

A shameless plug for my business - visit www.magazineexchange.co.uk for back issue magazines - thousands of titles covering cars, motorbikes, aircraft, railways, boats, modelling etc. You'll find lots of interest, although not much covering American buses sadly.

I think the deflector has more to do with trying to keep the back of the bus clean than aerodynamics.

Len,
I must agree with you that an air foil will not do much to clean up the aerodymanics of a 96"X144" brick going down the highway.

I would like to know if the mirrors matched the color under the white paint.

Whoooaaaa, That is some color on those mirrors.

Also keep in mind that unless positioned properly an airfoil does as much or more harm than good

i am pretty sure that air foil-wing is stock when i scraped my 4107 under the rear cap that we took off there was that wing it, may have not been that bold looking as that photo but it was there!
Never stop thinking,it"s what keeps us going till tomorrow

i CAN GARAUNTEE!! that that air foil is not anywhere close to a GM OEM part in any line that they make/made including cars.

the lip on the rear roofline is OEM however but thats not what we are talking about

Whoops,  I threw away a roof scoop that was on my '06 when I got it.  I capped the rear and didn't want weight and leak suspects.  I thought it was to keep the rear window clean?  By the way, how do you include a picture in these posts?   Bill T.

Lots of information on the help board regarding how to post and how to re-size photos if they are too big. Here is a start:

Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body. But rather to skid in sideways, chocolate in one hand, a good Reisling in the other, body thoroughly used up, totally worn out and screaming:  WOO HOO, what a ride

Actually, the 4106 is so fast, it needs that rear spoiler for rear end traction at high speed.
