2008 Mercedes S550 with 150,000 miles

This all depends on condition and on how well it was maintained. Since maintenance and repairs on this car are astronomical most cars are neglected and become a money pit. If the car checks out and you can get a copy of the maintenance records and have the money for repairs you should go for it.

How long it lasts will be up to you. If you drive a lot and neglect it, it may be dead in less than a year. If you drive 5,000 miles a year and take really good care of it, the car might last another 10 years or more.

I had a coworker who bought a similar Mercedes. He was in love with the car and took care of it like it was solid gold. He ended up spending his life savings keeping the car going but it was a cool car!

As the owner of 2 SL550's - I can agree with F_O_R. Easy and steady driving along with normal maintenance - these could last forever. Clearly the last owner(s) did not let their car sit. But you have no way of knowing how they drove it. Unless you can get records of the brakes being serviced, Transmission flushed (VERY important), even if the Hard Top motors or suspension bags have ever been serviced. Just to name a few. I think I would probably pass on this one because there are just to many unknowns that could cost WAY more than you ever paid for he car. After 2 SL's, I would not have anything else - but find something newer with less miles.

With every used car there is a degree of service maintenance required. Whether it be a Chevrolet impala to a used Rolls Royce and everything in between. I bought my S550 with 113000 on the dash. It did need a few things immediately, an oil leak on the motor, had that repaired w a welding job. A new serpentine belt, A brake caliper, a radiator.and an oil change The car has traveled to Peoria IL twice. Madison Once and I always put it on the Highway. It is a very nice car, I drive it attentively and as I am 66, I really am comfortable that this will proabably the last car I expect to purchase for a long while , if ever
