A 850 is a very odd car to be a "company car". Unless,of course, the company is Volvo. Are you sure they're not handing you a line?? Check that the odometer is really working during the test drive. At 90K miles the timing belt 70K mile replacement could have been skipped. Check for the replacement sticker. It needs to be done ASAP which is a 4-5 hundred dollar job. You should be able to use this needed service to further get the price down on this already overpriced car. Check for burned tranny fluid. "Company" cars tend to get both driving abuse and short changed in the maintenance department. Take care and look closely.
