I chose a moderate priced 1:43 diecast automobile from American Heritage Models and an expensive priced one from Brooklin with the intent of comparing the value difference as it pertains to O-scale model railroad layouts. (understanding that 1:48 choices are minimal at this time.)
Here they are Head-To-Head:
On the left is a Brooklin 1:43 diecast 1954 Buick Century 4-Door Sedan (msrp $134.95) and on the right is an American Heritage Models 1:43 1950 Ford 4-Door sedan (msrp $29.95)
Both cars have, what I can best tell, about the same level of detail. The pics tend to confirm that:
One discrepancy with AHM Ford is the size of the antenna on the correct side of the car. It looks about 4 or 5 times too thick for my eyes.
Brooklin took on the difficult task of recreating the Buick's chrome waterfall grill. It is far from perfect, but a reasonable attempt. North of $100 should have been a little better, IMO.
Too small for a pic, but the license plate of the AHM Ford was higher detail than the Brooklin Buick. I could read NY 50 (top row) and SN1262 (bottom row) on the AHM. There was only one row readable on the Brooklin: BKN 180.
Interior detail was very similar, but because the AHM Ford Sedan had its front windows down it was easier to see interior details.
An interesting discovery: The AHM Ford weighed 120 grams and the Brooklin Buick weighed in at 390 grams. The Brooklin is definitely paper weight worthy
