buying german cars and other costs..

Hi all,

I am interested in either getting a second hand BMW, MERC C-CLASS, lexus, or maybe a jag, or camero..

I have been told that japenese cars depreciate less in terms of being able to resell in a year or two.

Is this true, and secondly if anything goes wrong, will it cost an arm and a leg for bmw, merc and jag repairs/spare parts?

I doubt I'll be going for the warranty(or qualify for it).

What are the good dealerships for second hand lexus and bmw please?

And between merc and bmw, which is easier to sell/depreciates less?

thanks very much
