Sums it up perfectly IMO.The non turbo early cars probably the most reliable - then go downhill as you increase the power & complexity going up the range.
But all these care are 9-16 years old now, so you will have all the age related stuff just like any other car to deal with, then tack on the hard top folding roof gubbins.
I've owned a few & all were great, but keep on top of maintenance & set your expectations properly.
If you go out seeking the cheapest in the country, don't expect it to be cheap for long.
