You might want to check with your insurance company regarding the legality of the rear SL jump seat. The car was not designed as a "four" seater and thus is not classified as such. Also, you will have to install aftermarket seat belts and these also will be subject to scrutiny. Is a MB dealership going to certify that therwere professionalyy installed in case of an accident and the impending insurance investigation? And God forbid..you had a child in that seat and was hurt or even worse...your life would definatly take on a different direction. If it's four seats you need, then look at a sedan.......but I caution you to investigate about adding the "jump" seat for passengers....
