Hello , Iam new at this site, however I have found it most helpfull in all questions i have wanted too know, To the point now, I bought a 95 sl320 which is the finest auto that i have ever owened! what i do not understand is the young folks wanting to change to bigger rims such as changing from the stock 16" rims too larger? Is there a reason in preformance and or handling ? or is it done for gas milage. thank you for all the wisdom. n.j horst.
