I wonder. I like FGCs and I am prepared to put up with less reliability than I would with a Japanese car. BUT my family unit is, nowadays, low mileage. I don't thing we have done more than 20K between the two cars in any year since I retired.
Our Fits have not had ANY work done except regular servicing and 2 recalls on the 2007. So my experience is probably atypical.
Now, I happen to like French cars...I drove one, different each year, for a month each year from '85 to '03. In summer, no bad weather, they were either new (TT plated) or rentals. If French cars became available in Canada in all their varieties I might easily change my allegiance from VAG to a Citroen or a Renault. I wonder what the 'unreliable FGC' brigade would say then. I bet that FFC would very soon be a buzzword.
Maybe I'm just lucky, but I added up my "Euro car years" and kms:
98 - 05 VW Golf, 125k
04 - 11 Saab 9-3, 165k
05 - 14 Saab 9-2x, 230k
11 - 14 Audi S4, 70k
Over 20 yrs combined and 600 k km's.
The 9-3 was the only one I didn't buy brand new and needed the most repairs (~ $2k non-warranty, non-wear and tear items). Also the only one I've ever needed to get a tow for (when the turbo failed 2km (yes, 2km's not 2,000km's) before the warranty expired). Could possibly have driven it but didn;t want to turn up at dealer 5k over the warranty rather than 2k under it).
So, I think maintenance is critical on them, and I'd be wary of buying pre-owned, but choose your model (not first year, not too loaded with gizmo's), RTFM (and follow the recommendations), and reliability is great. Along with the low cost of ownership from having quality parts that don't wear out so often as a lot of more cheaply made cars.
