Not sure if I want to like this car or not. Like everyone on here, having a close affinity to the mkiv, I wished for a great mkv. This car doesn't appear to be great.
First impressions are that it looks like a re-skinned Z4 (because it is), with the current fashion of needless bolt-on fussy body work. Looks awkward in the photos, but maybe better in the flesh? My current fun car is a Lotus Evora, which I think looks a bit challenged in photos. However, in the flesh I believe is a very well proportioned, good looking car that never fails to get positive comments - a mini supercar that often gets mistaken for a Ferrari or Lambo by those that don't 'know' cars. Hope for the mkv? Perhaps. I think it could look OK in lairy yellow, with a BGW, some better wheels and something done with the bumpers.
Interior. Anodyne, dreary BMW. No hiding from it. My daily driver is a BMW, and whilst it is OK, has very little excitement factor and is lower quality than a Lexus. But the mkv is a 'Toyota' and not a Lexus. It would have to be put up with.
How will it perform and drive? ..... Probably better than most mkivs. I loved my mkivs, but times move on, and this will likely handle much better. The relative 'low' power of the launch car would probably beat a BPU mkiv in all situations. I imagine a remapped mkv would probably beat single mkivs in situations other than a rolling drag. Real world, probably a better car. (But not a legend).
If I had 50k, would I buy one? No. I never buy new cars any way, but the mkv has a whole hint of 'meh' about it. It had impossible expectations to follow. I think the Toyota/Lexus positions are slightly changed from the early 90's. A Toyota can not be perceived to be as good as a Lexus nowadays, whereas back then Lexus were more concentrated on the luxury cruisers and stronger Toyota sports cars could exist.
