I stumbled across a gem recently and thinking about making the offer to the owner of a 1975 450SL. White with black leather interior. 107,000 original miles. One owner. Little old lady car. 100% original. Texas Car. Need your advise about possible value before I make an offer.
The car has been parked with a tonneau cover in an enclosed garage since 2005, and she starts it occasionally. Definitely needs a new battery, tires, some surface rust on the doors (it was parked dirty) but there doesn't appear to be any rust on the pans. It has the hard top on it right now and the convertible top is rotted.
What do I need to look out for when inspecting this car closer?
She hasn't started it in a year. My thought was to add fuel stabilizer, manually turn the engine over a few times to lubricate the cylinders and heads before putting in a new battery to crank it up.
Is this a good investment grade car? I don't want to insult the owner by low-balling her but its hard to think this car is worth $10k that is quoted by NADA guide.
you posted this in the wrong section
Just bring a battery and try to start it up. don't worry about hand cranking the engine. I had looked at older sl's for a while and did a lot of reading on them. They are old cars that will need quite a bit of upkeep to look nice and keep road worthy.
your looking at $1000 easily for tires, top, battery. Need to give it all new filters, fluids, tune-up, belts, vacuum hoses, other random rubber pieces ALL the fluids will be disgusting so it might take 2-3 changes to get them clean. I'd run 3 quarts through the engine after draining and before filling to get crap out, flush the radiator, change trans fluid/filter and check it after 1k miles. run fluid through differentials. Probably around $2000 doing it all yourself
to do it yourself. check the car for rust by pulling up carpet and look EVERYWHERE especially underneath. Rust is a pain and expensive to fix. push on the hood and trunk to check the shocks.
If you get it running with the battery check your engine oil and trans oil. listen for vacuum leaks and make sure your gauges work
What condition is the paint and interior in? both are expensive to fix. if the seats arent torn and the dash doesnt have cracks your okay. sounds like the paint isn't in good shape. A good respray would run you $6000.
Basically need to see detailed pics. I think your better off waiting for a cosmetically mint car. it's be helpful if you told us your budget and intentions for the car. good luck
