Hello all I'm looking to buy a 1994 Mercedes s420 it needs a.c. work and 2 window regulators replaced and he wants 2000$ with 129k miles I'm wonder if this price is worth it and how much I'm looking at putting in to it also how much is the regular maintenance on it I'd appreciate any advice you guys have thanks ?
The advice already given is good, add too it common failures for 94-95's that your PPI should look for;
1- All three wire harnesses in the engine compartment, Engine harness, Starter harness & ETA harness - all need to be replaced if original from factory, original wire insulation is bad and wires will short out.
2 - A/C Evaporator - All of them will start to leak, factory originals need to be replaced
These items alone could be another $4 to 7K depending who does it. Most likely the A/C problem is a leaking Evap, requiring to pull the entire dash assemblies out of the car to get access to the bad evap. Change all of the vacuum pods while your there... easy $2000 job, probably a lot more at stealership, mostly labor by the way, if you want to do it yourself, the parts are probably 300-400..
3 - Looking for a mid 90's benz (any model), is best advised to find one that the owner has already made these common repairs.
If this work is needed, you will be spending more in repairs than the blue book value...
I would rather buy a 98-99 model that didn't suffer from these problems.
