The answer is yes but its the same for any car. You'll see plenty of issues on any forum because its the first place people go when you've got a problem.
But you've got to balance that against the low purchase prices these cars go for at the moment. You are buying a future classic which will lose very little in value, downside is you might get some bills .
I've had 3 and covered about 70k miles and probably spent a couple of thousand other than normal servicing or normal wear and tear items, tyres etc so not bad .
