I have a tow bar and crossmember for sale for a 300 hatchback, I'm unsure if it fits a saloon but it's on a hatch at the moment.
It's in good nick (it is fairly chunky after all).

I'm looking for £30 plus post for the whole thing.

Ok man, many thanks for the pm - I might be half-interested in a tow-bar if no-one else wants it and I guess it won't add too much weight to the springs!! About the cross-member thing: is that the cross-member for the car that the wheels and brakes fit to (??!!) or is it a smaller cross-member type-of-thing for the tow-bar. If the latter, I could probably cope, otherwise, probably not.

It's the crossmember for the tow bar, there's a bar that goes behind the valance and an A frame type thing that goes further back under the boot.
It is quite chunky and probably weighs a fair whack but I'm fine with lowering price to accomodate since you are having quite a few bits off me
I'll get pictures of everything including this for you tonight.

The towbars are not interchangeable between a hatch and a saloon, sorry.

Thanks for that, I can understand why just wasn't 100% sure.
