Agree. When researching Citroen C6s, (as a long time Citroen fan/owner-DSs/CXs....) I read some bad stories, but also some inside info. Citroen has habit of spoiling their cars by a 'happorth of tar'-i.e. not getting the little things right. Until later.....when reputation is shot!
In contrast, I have this image of teams of obsessive 'Kaizen' operatives in Toyota, trying to get each nut.....perfect! Especially on the earlier cars, when they were trying to outdo everyone to PROVE their cars were best.
And, as you say, Phil, I asked Lexus Bristol (where I live, not far from M5 J18), their engineer said he'd only worked seriously on ONE engine (who drove through a flood!)
I guess the trouble is that, as I feared with my previous cars, the little bits that wear CAN add up to a fair few £££s!
I've come round again to the idea that something special is worth investing in!
