This thread was better than TV yesterday.
Seriously though you are not going to have any luck at all selling your cars here me thinks.
For starters the price you want is ridiculous. The car itself isn't half bad but it has been built and run by you, which is not really an indicator of quality.
Second, all the tat that you have attached to it doesn't really make it any better. Granted, the shocks are necessary and the T-plate is a nice touch but all the rest is just pointless.
I'd be surprised if you find anyone willing to pay even the price of the new kit for it. I think 45 pounds is just about realistic and even then I wouldn't touch it with yours mate.
Try and find a forum you haven't posted on yet and try and sell it there or as an even wilder idea just drive the poofing thing yourself.
You are so going to hate 4wd and I dread to think of what you will do to the poor kit that makes it's unfortunate way into your home.
