I should mention that the difference between best and worst reliability is less than it has probably ever been and Japanese manufacturers are to be credited for raising everyones game.
The build quality is still too variable and the worst car I have seen recently in internal build quality has been the Chrysler Sebring which has mismatched and poorly fitting trim made out of cheap plastic with hard sharp edges. They are misguided in bringing that into the UK because I forcast that it will not sell in any numbers. The 300C otoh is a car that I would seriously consider with the Mercedes V6 turbo diesel and selectronic gearbox. Nice.
We're comparing brand names where data is specific. It's not a US vs Europe vs Japan.
The difference between a LC100 and DiscoII is about 3:1 in repair reports. 3x is a significant number to me.
A 1997 Lexus LX430 has fewer reported repairs in 2006 than a 2005 MB ML320. A 9-year old car with less issues than a 1-year old MB. I won't own garbage.
