Hi, I'm new to the group and last night facilitated the purchase of an '86 420SEL for my 18 year old step-son. It's in great shape, the interior is like brand new, has 120,000 miles and so far I've been unable to contact the previous owner to get the history (but I'm still working on it). There are a couple of little things I'd like to fix up and figure out so I need a little help.

I did a search on the VIN through a website (can't remember what one) and it comes back saying the car was a Diesel. Anybody know where I can find out for sure if this is true and I've just bought a body shop special?

There was no owner's manual in the car so trying to figure out the knobs and controls is a little cryptic. Does anyone have a manual they might be able to scan and email?

Power locks all work properly except for the driver's door. It doesn't lock or unlock any other door.

Passenger seat recline works fine going down but you have to hold your mouth just right to get it back up. So far, neither my s-son or myself have been able to find the sweet spot, only the lot boy was able to.

Any other suggestions regarding keeping the car looking and running well with as little expense?

I'd appreciate any input and thank you in advance.

Geno.
