So i took your advice rob. Picked it up today for 180 brand new in a shop in airside that sells and repairs pressure washers.
Gave the car a quick wash with it today and its decent enough.
He has the c110 and c120 there in stock aslo starting at 130 which i think it good value. he can also make hoses for £3 per meter so i'll be investing in a new, longer more flexible one in the near future
