I bought a 214SEI from an elderly neighbour. It had sat in a heated garage and done around 500 miles a year on average. He had it main dealer serviced every year at first and then every two years. I kept it around five years and it cost me nothing more than oil and filters. Family problems meant that I had to get a wheelchair access vehicle or I would still have it.
Another low miler was a 25. It had been kept outside and within 12 months had ALL the known 25 faults and started rotting from the inside out!
Look at each vehicle on its merits and take your choice. Look at what are in the scrapyards and ask why they are there!
MOT history is handy when you see the same "advisories" coming up year on year! Tells you a lot about the mindset of the previous owners!
