You're right, they're not cheap. Therefore all the MORE reason to have made a longer trip to secure a test drive. A 50 mile, 100 mile, 200 mile trip even, made just once would've given you those answers.
Buying without first trying is just an anathema to me. "No drivey, no buyey" as Paddy McGuinness never once said 😆
But as you say though Mrs Jassy's happiness is all that matters and she sounds like my kind of driver 👍🏻
