BYD Seal vs. CLA 250+ (UK)

Tomorrow I'm test driving the Seal Excellence and the CLA 250+. The difference in performance will be massive, but I'm interested to see the differences in build quality and driving experience. In my head I've already made the choice, which is the Seal but I'm still going through with both tests.

I love the range of the CLA, but I don't like the idea of having to wait for another 6-8 weeks for a factory order to arrive with the 400v architecture converter (UK stock CLAs can only use 800v rapid chargers, the 400v converter is a factory option now)

I love the BYD for performance and just how utterly bonkers it is in every single way, but I don't like the relatively poor real world range

I'm coming from a 2023 A5 40 TFSI S-Line with every option ticked that I've owned from new, so I'll need something special to get me out of what is a sublime coupe / borderline grand tourer.

Has anyone else moved over to a BYD Seal from Audi? What did you think?
