it's easy-price out ball joints, bushings on both cars. then do the same with ac evaporators. you WILL have evap issues with the mb. include the labor. then, remember the harness issues, 81-87 on Volvos? mb had the same problem, using the same vendor, 92-96. working on both since 85, i'd stick with the 240s. pound for pound a 245 will do better, longer and cheaper, than any mb wagon. much LESS planned obsolescence with Volvo. good luck, chuck.
