The asking price is consistent with a price, when new, of below £18,000 and depreciation of 15% per year for 9 years i.e.
18000 x 0.7 x 0.85 x 0.85 x 0.85 x 0.85 x 0.85 x 0.85 x 0.85 x 0.85 x 0.85

Personally, I would be chuffed if a car lasted 70,000 miles on its original clutch so I would expect 140,000 miles to be the end of the line for its second one. In other words, I would want to see the clutch replacement paperwork in the service history before I bought the car.
Likewise, wear and tear replacements of suspension components would have been done. Steering can't be far behind.
If you think about it, the big servicing bills are -why- people with more money than you offload their cars at a certain age.
15500 miles per year would make it a rental, as suggested elsewhere, or a rep's car or someone commuting 20+ miles per day (which may or may not fit your locality). Not enough miles for it to have been a taxi.
Finally, the length of warranty offered speaks volumes for what the dealer thinks of the car. If you go there for running repairs they profit from you a second time. You are under no obligation to go back there and a free to shop around for better prices.
As for redress, the car did what it said on the tin - it lasted three months. Was it good value at that price? Perhaps not but, if it freed you from having your workdays dominated by the bus schedule then perhaps it was?
