A little too big for my tastes. Pre-50's cars ARE large and always look large next to people, but when the hood is over head height it also very occasionally can cause mechanical issues in games (i.e. shooting from behind a hood should count as cover and not as fully blocking terrain). Of course if you're playing only with people you know well, that shouldn't be an issue, but there are enough cars and trucks that do fit well that I don't mind sticking to those. Also, if the cars are too big they really make my buildings look small, because like most people, my buildings are already at a greatly reduced scale to fit on the tabletop usefully.
As a general rule I go for three things: Hood is under head height, tires up to roughly waist height (for cars more so than trucks), minis look like they could actually fit inside (this last one disqualifies tons of smaller cars, like the Lldeo lineup). And I guess I also go for "Looks like it could match my existing fleet".
But it's a very very very nice model. It looks perfectly fine if you don't mind the scale fudging. Lots of people are totally okay with 1/43 vehicles.
