I'm looking for a car to replace my 86 300E that was totalled last year and found a 92 300E for sale. Are there any particular problems this year had that I should be aware of, i.e. disintegrating wiring loom, leaking head gasket, valve guide seals, etc.

Does it have the same M103 engine that my 86 has? Is the M104 a better engine, reliability-wise?

Are there any significant differences between the 86 and 92?

I had bought a complete Sportline kit just before my car bit the dust and it was never installed. Will the same parts fit the 92?

What would be a reasonable price for a low mileage (under 90K) car in the L.A. area? (not sure at this point if it has service records or not)

Thanks for any help
