I'd have to agree with the sentiments about the main dealers: I bought my 406 2nd hand from a main dealer and had a years warranty. It started losing coolant at 11 months; put it in for them to have a look and guess what, they couldn't id the fault. Given that there were no external leaks my guess was that it's a leaking head gasket - but the delaers response was that although it probably was this, they wouldn't proceed under the warranty, I'd have to go ahead at risk. That risk equals maybe =A31200. Not an option for me, too expensive. Two things here - 1) the 2nd hand warranty is s**te 2) the diagnostic service is s**te.
However - my wife bought a vw polo from new a few years back and this was infiitely worse than my pug; endless major, costly problems and the main dealer service was truly appalling. Within 3 years we were replacing things like ABS computer, electronic fuel management computer and so on, things that should last the life of the car. The central locking has recently packed up and if you look around a breakers yard you'll soon realise that this is extremely common - these parts are always gone from the vehicles, like gold-dust. Bottom line for me is that whilst my pug is currently a pain, I can get my head round a blown HG, and once fixed am sure the car will plod along for years and years, whereas the VW will probably be in the breakers by the time it's 7 or 8 years old.
