I had a couple of 240's for many moons, I think 178K and 215K. I used a site called www.swedishbricks.com.
I found it helpful to have 2 like vehicles, so you can swap computer components, which seemed to be a weak spot for me.

Enjoy...those cars would put out heat in 2 minutes on a cold day, great heaters.
