Hi, I'm thinking about buying a Q60 convertible. It's a 2015 and is basically brand-new. I was pretty comfortable, but after reading posts about top problems with the car now I'm concerned. I have a Lexus SC430 right now and it's been awesome! Any advice would be appreciated. Are the convertibles really problematic? I don't want a $$ pit. I read the post from the mechanic who suggested an extended warranty. It would just seem that if the tops are that problematic, it wouldn't be worth it.
