Smile Getting '73 450 SL on road after 5 years

Hello everyone,
Going to be getting my wife's 1973 450 SL (automatic) out of storage after 5 years to enjoy the summer weather with the top down and was looking for any advice on things to replace or inspect to get her running again. She ran pretty well before it was parked. Only issue it ever had was bad starter that got replaced. I'm anticipating the worst but hoping for the best. Car was in really good shape. No visible rust, interior was really nice and had newer benz rims/tires. I'll try to track down photos.

My list included:
New battery
New belt(s)
Distributor Cap/Rotor/Points
Change Oil & Filter
Inspect tires/steering/suspension
Fresh gas
New air filter
Check & top off fluids

What tranny fluid should I use in an auto if its low?
Any well known issues to look for on this model?

Hoping all goes well so it doesn't eat away at my '68 Mustang resto budget but we'll see. Thanks in advance.

re-prioritize the list

Check & top off all fluids
New battery Start and warm up over 1/2hr
Inspect tires/steering/suspension
Change Oil & Filter

The above is required

New belt(s) (maybe)
Distributor Cap/Rotor/Points (maybe)
New air filter (remove blow back thru)

You may be stunned to know some of the cars I've made run before doing everything, take it a step at a time.
Unless your first ride is a thousand miles.

Wink Ceramic Fuses

Those old fuses can oxidize when sitting up for long periods. It would be a good idea to replace them now with new ones. They can look "okay" but still fail. It usually happens at the worst time, fuel pump, window regulators or lamps don't work.

I would also highly recommend a close look at the brake fluid and brake lines. MB usually says two years for a change out of the fluid because of the water it will pick up. The hoses and lines can cause all sorts of bad things to happen.

Pretty. Hope all goes well. I am also restoring a 76 450. Took it out yesterday for first time since I rescued it several months ago. Needed a lot of new wires and hoses. Rats dined at the Benz cafe during prior owners reign. Now it needs new belts and tires. Good luck to us both!!

I am also restoring / repairing a 1973 450SL that sat for 8 years. I needed to replace the water pump and had garbage in the gas tank. At least put some fuel conditioner in the tank. At worst drop the tank and have it cleaned professionally.

You might want to go over to the 107 forum, there's a lot of people there that have a lot of experience. They can help a lot.

A lot of very dedicated people.

Remember: It's not just a car. It's an Adventure.
