Having finally bought a 335i a couple of weeks ago, i can now finally join the thread
Tax £94.50
Insurance £368
Coolant £12.04
Cant say im massively impressed with the coolant scenario, had a check/drain/refill and new radiator top hose at BMW 2 weeks/300 miles ago; but had nothing in the header when the light came on yesterday morning (took 1.5L to fill up)
