Hello again after a long intermission
I'll preface my response by saying good riddance to 2016
Anyway, my 1978 280SEL cost a good night out under 4K, and then about 7K thereafter, including a Sanden upgrade a/c and refurbish, lots of front suspension work, accumulators, new battery, various bulbs etc, lhs sls shock, new exhaust, warm up regulator (2), work to the ignition and injection, and a couple of thorough services. Also I had to replace the lhs rear door after someone ran into it two days after I got out of hospital in March last year. When I list it - and keeping in mind all I've done is make the phone calls - this sounds like good value.
I'll soon be spending a little more putting some good tyres on the 15x7 Rial wheels I acquired when getting hold of a new door after the bingle. The door and wheels of course came in the form of a whole car, and then immediately after purchase (a 450 SEL import) , a good door emerged . So the on selling of the lovely 450SEL will hopefully somewhat offset the total cost. But I'll miss it.
All small beer considering I've owned a Porsche (increments of 5K), a SAAB 900 turbo (actually very reliable), a Mk 7 Jag, an Audi 200T, WRX, etc
If this is a competition - and I don't suggest it should become one - first prize must go to anyone who has had their W116 professionally restored. I take my hat off to you - especially the 450 from - I think - Ireland.
