As above, to suit a 7 / Jago / normal car.

Anyone know of anything for sale

How much are you looking to spend? I might be selling mine. Its a single axle (landrover) with suspension and brakes and can carry a reasonable size car, I had an MGF on there easily.

Im also selling a big trailer that could move cars. Its a flatbed, 1/2" ply base, beavertail back, twin axle totalling 2.6tons. Antisway hitch. Needs a bit of finishing like lights etc, but the frame is freshly painted. I paid 500 for it.
