The 380 doesn't have a radiator that has a core that can go rusty, surely?

I would think it's more likely that the coolant has gone off, you just need to flush and put fresh coolant in. No need for new radiator, hoses, thermostat etc.

The rust is from the motor, not the core as the core is alloy.

You will find the rad a fun job, front bar off, complete rad support off, undo air con condenser from rad is a pita and after that is a usual radiator removal

If the coolant has gone corrosive, the brown is probably corroded iron and aluminium (rust from iron is brown, corroded aluminium is more red in colour) and it will come from a lot of other parts than just the radiator. You could pull the thermostat out and look at the housing, the corrosion you find in there will give you a good idea of what the water passages in the heads and block will look like.

I would change the coolant quick smart, leave it at that, and keep my fingers crossed no problems surface arising from corrosion.

(Mal beat me to it. When I look at a second hand car, and I see coolant that colour, I walk away quickly no matter what the price is. When cars first came out with alloy heads, some owners were not aware coolant was needed and just used tap water. 18 months of tap water was enough to corrode the heads so water went into the cylinders. And old coolant is much more corrosive than tap water.)

I wouldn't drive the car at all like that.
Worst case scenario is, that you will be ringing around the wreckers for another motor. Or pulling the heads off to get welded up, and replacing numerous alloy bits on the engine.

Have you got a log book/service manual with the car? I'd love to see how old that coolant really is.

Seriously, this is something you need to attend to as soon as possible. Just because the car is ok today, doesn't mean it will be ok tomorrow. Rust never sleeps . . .

You could keep driving it as is, but when you see oil floating on top of the coolant, or find frothy white goo on the inside of the oil cap, or water sprays continuously out the exhaust pipe, you know you have left it too late.

Not my car, don't know why I'm getting worked up over this.

Sounds like your mechanic stitched you. When I get cars in like this I will only offer a full cooling system overhaul or I won't touch it
