I feel like it's one of the best cars on the market.
Some of the problems with the 7 series BMW is they have a plastic valve piece thats starts to crack after so long causing them to blow out white smoke from the exhaust. It's not a blown head gasket. But for them to change the valve it's going to run you about $8, 000. BMW are not cheap repairs sometimes. Just keep up with the maintenance and be prepared for a rainy day. They do drive the best though when everything is running properly. Very smooth on the road with a lot of power.
