some of them were different but for most like the, lamborghini and the 348 the way to tell if its a twin turbo is to look for the side bumpers in front of the rear wheels, a wider wheel base and a short front bumper. That one appears to be a twin turbo all tho it doesnt have the side bumper, i dont think any of the f40s did or the porsche
I wish I didnt see that sell for just $41.00, thats a total steal
