Brand of model vehicles that include working front axles? (axles that turn)?

Are you referring to steerable front wheels? If so I have been successful in creating this look by simply taking the front wheels/tires off and reattaching them in a turning stance...the look is quite suitable for a static model.

Flanger, 

IMHO, I believe the OP was hoping that there was a company that made O scale vehicles with front wheels that are on a pivot, so that a magnet can be attached to the bottom of the car and beneath the layout to create the effect of a moving vehicle. 

Downeastcapitol, 

I do know any brands that have the feature you're describing. I myself would be very interested if such vehicles exist. 

Bob, that's a great idea. I hadn't thought of that for static scenes. I haven't begun to build my layout -I'm still planning, but I will definitely use that technique when I get there.

Dan, yes that is exactly what my current project entails. If I find something consistent I will be sure to post it here, but at this time the only option I am sure of is SuperSlicks and other 1:43 R/C cars which are $25 to $35 a pop. It's a bit expensive for me as I would only be chopping them up for parts. That said, an HO scale Faller car is often over $100 so it may not be too crazy

slot cars have been commercially produced in 1:48 scale and 1:43 scale, corresponding to O gauge model trains. 1:48 cars were promoted briefly in the 1960s,

If you can find them  they sometimes had headlights and tail lights.

Motorific.

I wasn't aware that slot cars normally had steering. None of the ones from my childhood did! I'll look into this. Slot cars are also way cheaper than R/C cars on eBay and they have the tires I need to boot

Thank you, Sirs

I remember having two motorific vehicles growing up.  A Camaro and a blue and orange work truck, Highway Department I believe.  Those things must cost a few $ if you can find them.

Some late 60's era king size Matchbox cars and some Corgi vehicles had steerable front wheels. I had a Charger, Cougar and police car with that feature. The only manufacturers I know of that have possible front wheels is First Gear, TWH/Sword, Conrad and possibly Joal. And these are mostly service, construction or emergency vehicles.
