Just picked up this Tomica Premium NSX from a friend. Thought I'd show the difference in quality between a few different 1/64 models at various price ranges. I really need to include the 1/64 Spark model for comparison, as it's pretty darn detailed too.
Hot Wheels 934.5- $1
Tomica NSX- $10
Tomica Limited Vintage Neo Silvia Super Silhouette Racecar- $70

Quick pic of the trio.

The detail and finishing aren't even close, but that's to be expected.

One of the coolest features of the Silvia, the removable front end. Motor isn't too detailed but I can't complain!

Pretty cool with the detailing on the rear with the tail lights and accents on the NSX, look smuch more complete.
