Answer
Kim, personally I would stay away from that thing.  You are asking for problems.  If you have an abundance of money to get that thing up to date then by all means, buy it.  Just to give you an example.  The control head for the A/C heat etc is a common failure and just the part is 600 bucks.  Used ones are very hard to find.  If you want to buy a used Volvo, then get a 240.  You cant go wrong with that one.  Roger
