Not a "daily driver" to & from work, anymore, but I sure do get it out three or four times a week...
1973 Mercedes Benz 450SE, the 1973 "European Car of the Year" (which also happened to be the year I graduated from college) which has a mere 280+K miles on it. Bought about 4 years ago, two AutoRx treatments for the engine, one for the tranny. Using (now, anyway) a mix of a gallon of Delo 15W-40 and 4 quarts Chevron Supreme 10W-30.
It had almost new 70K guaranteed radials, brakes are fine, one transmission service, replaced three brake lines, changed the differential lube, new battery, & keeps eating speedo cables, may be due to the fact the guy I bought it from had rolled/replaced the speedo... When I finally caught up with him, and thanks to a sting we set up with local law enforcement, he spent over 4 months in the county jail before he finally posted $13,500 (1/10th his $50k bail for the 4 Class C felonies he was indicted for in regards to this fraud and identity theft incident, 1/10th his $85,000 bail on an outstanding fraud warrant from Arizona) 2 weeks before the trial date: he then promptly scooted off to sunny Mexico...
A/C works, sunroof works, power windows work, speeedo & cruise control don't. 10 mpg on regular around town. Leather seats need replacing but I thinks I'll wait another decade, or so...
All I can say is that if you have never driven a W116 series S-Class Mercedes you are missing an opportunity to enjoy what made these cars some of the finest machines of their era.
Cheers!
