I have a 92 300sl that now has 107,000 miles. I have had the car just shy of three years. I use it in conjunction with another car and try to drive it less than 1,000 miles per month. Overall the car has been great. I bought it in 2007 with about 75,000 and paid less than $11k. The repairs I have done include:
New hydraulic cylinders in the windshield top at 85,000 miles. The job cost $100 and I did it in about three hours.
Head gasket replacement at 104,000 miles. I knew it was coming for some time as there was a oil leak at the back of the block. Finally I got some oil in the coolant and had it done at a great Indy. Cost about $1,300 and the inside of the engine looked great. Of course the coolant was flushed and replaced. Be sure to determine if this has been done. If not, reduce the price as I understand that it is just a matter of when, not if, the gasket will go. Check with your dealers and Indies as to cost. I found the range here was from $1,200 to $3,000.
I have replaced a few rubber items under the hood as they get very hard and crack. Nothing major just $25 here and $25 there and 20 minutes of time. I have also replaced all the fuses with the copper style.
The hardtop headliner separated from the foam and it took an afternoon to fix that.
I am currently replacing the strut mounts.....an easy job at home.
I am due for brakes and have assembled all my rotors and pads, just waiting on another Saturday to complete the job. It last had pads and rotors at 55,000 miles before I bought the car.
I will also be servicing the trans, replacing the motor mounts, and flex discs. Not major items, but anything rubber based fails after nearly 20 years.
My biggest problem is that it won't go into fifth gear and the cruise control doesn't work. I understand they are related so I am chasing down those gremlins.
I have been meticulous on maintenance and the car asks for very little. Cosmetically the car is very good. Only interrior wear is on the drivers side seat bolster. Other than that the leather looks new. I will have to do a soft top but I will wait on that at least another year. I understand the wiring problems were with 93-95 so shouldn't be a problem.
The 300sl has great and seems to be less expensive to maintain and easier to work on than the other models. Gets very good mileage. I get 27-30 on the road without fifth gear!
