Have a '91 DeVille that I bought four years ago with 200,000 miles on it. Now has 257,000 and the 4.9 continues to run strong.

With regular care........they're invincible. You'll make 300k easy, but you'll most likely have to replace the trans at least one more time.

I don't think I've ever seen a 4.9 that had to be rebuilt. The most mileage I've ever seen was a '91 Seville with 360k, that was still running strong.

I had my transmission rebuilt at 216,000 miles. As far as I know, the engine hasn't been touched. Certainly nothing more than a tuneup and regular oil changes since I've owned the car.

It's at 257,000 now. I haven't driven it much since I bought my '01 Seville in February, but I'm hanging onto it to give to my niece in January.

I've got 284,310 miles on my 91 deville with the only problem being that I need a new ABS pump. I keep up with her as much as possible. Tune up twice out of the year and coolant changes being one in the summer and one in the winter. I've been through two trans. rebuilds one being at 136,000 miles and the other at 274,000.

My 94 Sedan Deville with the 4.9 has 291,000 miles. the engine is still incredibly strong running, and has great power. Very smooth and quiet.

I do need to change out the struts and shocks, as they are shot. I just became the owner this year, and it has been maintained, but it could be a much nicer car, if all the maintenance had been kept up better.

For instance, the leather seats are ripped on the drivers side, and the leather is dried out. I also had to have the drivers side seat frame fixed. When I bought the car, the drivers seat was propped up with a 5 gallon bucket between it and the edge of the backseat.:D
