I had a '79 VB SL (253 V8 manual), and this one looks nothing like mine. I agree with Ado's post, as it looks like there are a few things that are a bit different. The one that always stood out to me the most was headlight wipers. Why on earth you needed them I would have no idea. I think the only real noticable thing which mine also had extra and which some later model SL's also came out with, were the SL/E Mags instead of standard rims.
Still a nice looking machine.
