Good information so far.
As far as some stuff goes, I do realize these cars are 20+ years old and are going to have issues. I already have a very good shop I go to with my Ghia, they do work on Mercedes there. It's seriously the best shop I've ever been to for quality of service and customer service, these guys have gone out of their way for me more than once. Plus, I am pritty handy my self and know the limits of my ability. So I'm good there, I gemerally leave about $1,000/yr or so for repairs outside normal mantinance. Though my 92 Passat blew that budget to hell last year due to extreamly poor mantinance by a previous owner (one example: they JBwelded the waterpump studs back together after they were broken off in the block!)
Which leads me to the second bit, I am willing to wait to find a Mercedes that has been properly maintained. I'm doing my very best not to go impulse buy one.
As for the cold weather, I guess I'll have to look into something to get a little power out to the garage for that. Whith the added bonus of being able to use the electric start on the snow blower. (though it always starts on the first pull...) Or just plan on not driving it when it's super cold out...
any hoo, keep the advice coming, it really is very helpful. Thanks!
