Hello everyone:
Just checking out some prices on some goods and here's what I found. at volvo.autowebaccessories.com they sell the OEM loadbars for '93-'00 850/S70 (for Sedan, but can be converted for wagons with conversion kit) that don't have the rails for $116.15. You'll need to look up part number 9134647

Also, I found that the programmable wiper relay (850's and S/V 70's...maybe others) is really a VW part made and sold by Bosch and Audi among others...you don't need to spend upwards of $70 for it. Cheapest I found it was at http://catalog.eautopartscatalog.com/ipb/egermanparts/quote.jsp?header=&footer=Please%20Come%20Back%20Soon,%20We%20Appreciate%20Your%20Business!&product=357955531&partner=ipb&baseurl=http://www.egermanparts.com/&clientid=egerman&cookieid=1IN03IIXY1IP0T4TN4 for $32.00. This site has many other decently priced items. Bought a magnetic oil pan nut from them for less than $3.00. Total of $75 or over means free shipping.

Not affiliated with either of these places at all, but just wanted to pass on info that may be helpful to others.
