Time to Cut Bait? (E70 4.8i Issues)

[Pushrod]

Really appreciate some perspective from those of you in the know:

I have a 09 X5 4.8i (N62) that I have had for the last 3 years. I bought it with 47k miles on the clock and it now has 79k. It was a great truck until recently.

Back in 11/17 I had the dreaded alternator bracket oil leak. It completely blew and I had to get the truck towed. I took it to an indy, and they recommended I replace every other known-to-leak seal if I was going to keep the truck. So valve covers, timing covers, etc, all were replaced. $3400 out the door at an indy shop.

Then last week I notice coolant under the truck. On the way to work, the low coolant sensor came on. I took it to the indy fearing the worst. Sure enough, it's the dreaded coolant valley pipe leak. With a new water pump, thermostat, etc, it's another $2500 repair. Since the oil leak, I've put on less than 4k miles and will have spent $6000 in repairs on this truck. From what I can tell, the wholesale blue book value is in the $10k to $12k range.

I've owned several BMWs in the past, including several V8s, and NEVER had such problems. I'm really at my wits end with this vehicle, and have totally lost faith in its reliability.

I haven't authorized the coolant valley pipe repair, because I'd rather take that money and use it for the purchase of a different car if I decide to go that route, which is where my dilemma lies.

Do I fix the X5 and hope / pray / cross my fingers that I won't have another major repair in the next few years? What are the chances that another major repair is on the near horizon after fixing the coolant valley pipe and the alternator bracket seal? I've heard valve stem seals are upcoming, but they typically don't go untill after 100k. Seriously, if I have another major repair on it in the next year, I'll drive it into Lake Michigan.

Really appreciate your thoughts. I promised the indy shop I'd either pick it up or authorize the coolant valley pipe repair on Monday morning.

Thanks!
