Also should be noted that the Nissan VQ motor won the worlds best engine award many years in a row....
Look if you want a change in scenery go for it, I'm simply pointing out from FACTS that the recent crop of german cars such as bmw's and merc's have had questionable quality over the last few years due to their build location.
And James on re-sale value would say a euro loose more than an entry level bmw or merc in actual dollar terms.....Im not so sure....
(ie and this is completely made up...say if BMW 320 cost $50k new and resold for $30k as opp to euro cost $40 new and resold for $20k)
