hi im new to the site and although im running a bmw e30 at the moment, im looking at a few w123s in the 280 form, but was just wondering if its an option to change to a manual gearbox. are there any other manual gearboxes from other models that will fit the 2.8 litre, and if it was an option from new, are these gearboxes impossible to find or afford, any advice would be great cheers josh.
