What ant-freeze for 2003 MX5 Mk 2.5

[yottie]

I'm second owner of the car, it's done 35k and I doubt the a/f has been changed. Would like to drain, flush, and refill with new coolant. I'm confused as to the type recommended. MX5 parts say Mobil Concentrated but the postage is £10 ! is there a suitable alternative for this model.

Go for a well known make such as Comma 5 year - or any other anti freeze thats generally available and usually red in colour.
