Hi Peter,
As Mary said, I have used an XC90 for a few Years as a responder. The 70 and 90 share the same drivetrain with the only difference that the 90 has a bit more ground clearance.
They are very capable vehicles especially in snow/mud conditions with the tyres you have fitted.
As to vehicle modifications, I think you have done the most important one by fitting a decent set of tyres.
As you are in Malvern (worcs), you fall under our area (Gloucs & Worcs).
We don't really use CB anymore within our group as we now have our own VHF network. Radios will be provided by the group and can be fitted to any car as plug & play (ie via cigarette lighter & magmount aerial).
As Jamie mentioned, important part is the kit you carry mainly to keep yourself going.
Training will be provided, including BORDA and various others
If you want further info or interested in joining, please contact our membership officer (Pete Willis) at
