Took the Yukon to the dealer for driveline fluid changes and to get a couple of oil cooler lines replaced. They gave me a quote back in November for $1,900, so I took it to a local indie for a second quote and the indie was $100 higher. Anyway, today the dealer only charged me $1,650 - they had a line in the bill for a $250 discount. No explanation, but I'm happy to take it.
And while the Yukon was in the shop, I put that new water pump on the GTI. I'd planned on changing the coolant as well, but only 3L came out so I only put 3L new coolant back in. Oh well, good enough for now I guess.
