Nice! Congratulations on landing that Offenhauser. Doesn't that Ferrari 555 have the sloppiest front end that you've ever seen on a Cartrix? I can't believe how much up/down play there is in that.
But I'm right there with you, adding nine GPLs over the past few weeks, six via trade. (extra-special thanks to oceanview!) I also picked up a second DBR4 (sealed at the moment) to see if a stock one really runs all that differently to the Slot.it/BRM one that I tuned up. (center)

What's really impressed me is how far they've come on the detailing on the new releases, taking care to add far superior suspension details than their earlier models:

And the inside of the wheels are looking a lot better too. Check out the difference between the new Alfa's brake dum and the hollow wheel of the older BRM:

It's nice to see that they are improving their models instead of just pumping out repaints and enjoying the profit generated by their limited releases. It'll be interesting to see what changes for the better on future models. Cartrix is really doing a great job with these GPLs!
