Skoda 22nd of 30 Last year's position 19th of 26 Cars needing repair work 33% Average repair cost £196 Star modelOctavia ('98-'04)
Despite Skoda's traditionally good results in the JD Power customer satisfaction survey, it generally doesn't do terribly well in our reliability survey.
The ('98-'04) Octavia managed four stars out of five for reliability, with 23 breakdowns per 100 cars.
However, all of the other Skodas in the survey were given a two-star rating.
There is some good news, though, because Skodas had the lowest average repair bill this year, at a very reasonable £196.
Subaru 7th of 30 Last year's position 3rd of 26 Cars needing repair work 21% Average repair cost £595 Star modelForester ('97-'02)
Despite slipping a few places this year, Subarus still appear to be solid and hard wearing.
The cars had the highest average age in this year's survey, along with the highest average mileage.
The ('97-'02) Forester suffered only 12 claims per 100 cars, earning it a reliability rating of five out of five.
However, when things do go wrong they're likely to be expensive, because Subaru had one of the highest average repair bills, at £595.
Toyota 3rd of 30 Last year's position 2nd of 26 Cars needing repair work 16% Average repair cost £355 Star model Corolla ('00-'02)
Reliability stalwart Toyota managed just 15.73 claims per 100 cars on average.
It also had the most-reliable car in this year's survey, the ('00-'02) Corolla, with only two claims per 100 cars.
All of the Toyotas tested got a reliability rating of four or five out of five, apart from the three-star ('94-'99) Celica, which had 32 claims per 100 cars, with 53% of these caused by the axle and suspension.
The biggest single cause of Toyota's reliability problems was electrical faults.
Vauxhall 12th of 30 Last year's position 13th of 26 Cars needing repair work 29% Average repair cost £263 Star modelCorsa ('93-'00)
Vauxhall's smallest model, the ('93-'00) Corsa, turned out to be its most reliable, with 20 claims per 100 cars, while the later ('00-'05) Corsa wasn't far behind at 26 claims per 100.
The ('98-'04) Astra didn't fare quite as well, with a reliability rating of three out of five and 28 claims per 100 cars.
The least-reliable Vauxhall was the ('94-'00) Omega at 44 failures per 100 vehicles.
Volkswagen 20th of 30 Last year's position 15th of 26 Cars needing repair work 32% Average repair cost £264 Star model Lupo ('99-'05)
Volkswagen has dipped into the bottom third of manufacturers this year.
The only car to get a maximum five-star reliability rating was the ('99-'05) Lupo, with 18 claims per 100 cars.
The ('94-'00) Polo was the next-most reliable, with 23 claims per 100 cars.
The worst model was the ('00-present) Sharan, at 36 claims per 100 cars.
Electrical gremlins were the biggest single cause of VW failures.
Volvo 15th of 30 Last year's position 18th of 26 Cars needing repair work 31% Average repair cost £344 Star modelS40 ('96-'04)
Volvo prides itself on build quality, so 15th might look disappointing, but it's a better result than last year.
It had three cars with a full five-star reliability rating – the ('96-'04) S40, ('96-'04) V40 and ('92-'96) 850.
The 850's position is impressive as it's the third-oldest car in the survey.
However, the S80 was the flakiest Volvo, with 45 claims per 100 cars, and an average repair cost of £485.
