This is a fill-in-the-blanks exercise on page 56 of 新实用汉语课本5 (photo):
那种汽车 ____ 价钱很贵， ____ 的确质量很好。
We're asked to fill in the blanks with 关联词语. What's tripping me up here: if the 的确 weren't there, I would use 虽然……但是…… such as in:
I'm fairly confident this is unproblematic.
But the given sentence has 的确, and my 语感 is telling me that 虽然……但是…… is not compatible with 的确 here (something feels off, although I can't quite pinpoint what), and I should choose something else. Although maybe I'm "afraid of ghosts", and the 的确 simply adds emphasis to the right-hand side.
Question: Is it okay to fill in the blanks of 那种汽车 ____ 价钱很贵， ____ 的确质量很好 with 虽然……但是 despite the 的确?
