I drive one everyday, they rot same as any other mini
I'm afraid that just isn't the case in my experience. It's a well recognised that Rover recouped some of the development costs of the MPi models by making cutbacks on other things such as rustproofing and paint coverage. It's also suggested that some sacrifices were made in terms of the thickness of the panels that were used on the later models as well. In the latter days at Longbridge, there were even reports of unprotected MPi shells being stored in the open air outside the factory, before they were allocated onto the assembly line. Meaning that corrosion was taking place in some cases before the car had even been built, let alone before it had left the factory.
Something that I have noticed is that if you put your head inside the boot of an Mpi model and look upward at the underside of the parcel shelf and the inside of the rear panel, you will often see that the panels are barely covered in primer, let alone body coloured paint!
Of course you will always get good examples that have either been restored, or well cared for and have benefited from after market rustproofing, but those that haven't will generally be far more vulnerable to corrosion than earlier models are. Having looked over a few MPi models with a view to buying over the years, I have been quite frankly horrified by the level of corrosion that they have all had, particularly for such relatively new cars. In the cases that I have seen, I would suggest that the level of corrosion on an untouched Mpi, is generally comparable to cars that are around 5-10 years older.
