He may be saying how things are but to tell someone they should have bought a modern car and that they bought a cheap radiator by choice is arrogant. I posted so that other people would now about a problem not to be abused.

You are arrogant and presumptuous. You have no way of knowing why I bought it. For a senior member to take this approach to a junior member ensures that you drive away people with less skill than your own.

Less fun if the car is a daily driver and you are trying to fit it overnight with no brazing gear.

Be aware that if you buy a new radiator that comes from Britpart - it will not fit. The lower brackets are in the wrong place and they do not have any with the correct pattern. You either have to cut the brackets off and re braze them or find another source. Britpart not particularly helpful...
