Re Aston Martin reliability - from the site you linked to :"The UK Reliability index takes into account all factors of a repair, the *cost of the parts* and the frequency of failures"
Including repair cost as a factor is probably why Aston Martin are in the worst 3 together with Bentley and maserati, with generally more expensive cars showing as least reliable, with Daihatsu and Suzuki the most. But that's not what reliability means. The real measure should be number of breakdowns per distance driven or garage days per distance driven.
Note I'm not claiming Astons are reliable or otherwise, just that the measure on the site you linked to is flawed.
