Do you have any idea how this car was driven? Most guys drive the HELL out of them before moving on the next car.
First of all, I hear dismal things about these cars (everything under the sun), so I personally wouldn’t get one, but . . .
Pay a Mini expert to go over the car with a fine-toothed comb.
Find out if any/all updates have been done. There have been many, from what I understand.
Does it still have the first clutch? From what I hear, they don’t last, even if you know what you’re doing.
Run a carfax. You’d be surprised what sometimes comes up, but only if it’s been reported.
Set aside money each month for expensive repairs. You’ll need it, apparently.
I know this was kind of off the mark, but I just had to add my two bits.
Do some google searches on Mini issues, even if you do get the car.
Forewarned is forearmed.
