What's your take on your Infiniti? Best car (other than the Rover) we've had was an Acura but like the looks and reputation of the Infinitis.
For me and considering all models
Fit/Finish
Lexus
Acura
Infiniti
BMW
Never owned a Mercedes or Range Rover. Range Rovers have pretty horrible reliability ratings but I love their interiors. Some of the nicest leather.
My Infiniti has a lot more stuff but if I kept it for 100k miles I would expect Acura/Lexus to hold up better. We have friends with a 10 year old Honda Pilot that has 150k miles that looks brand new and not one squeak.
Bang for the Buck
Infiniti-They live and die by one model which they got right, the G37 sedan. Two good SUV's. Everything else is kind of blah.
Acura-Acura is doing it right with their SUV's but their sedans are just not competitive.
Lexus-GS is nice, new IS 350 is nice.
Mercedes
BMW-Always about 20% overpriced compared to Japanese. Their best models seem to be the cheapest models (1,2,3,and 4 series). M series are wonderful but again way overpriced IMO
Most boring
Lexus (Except the F models)
Acura
Infiniti
The brand that is finally getting it right seems to be Cadillac. Nearly bought a used CTS-V but the interior still seemed pretty junky for that level of car. I was impressed by the ATS that I sat in though. The big 3 have been nailing it on their powertrains for a number of years but some still have some work to do when it comes to interior quality in the luxury market.
