Just picked this up today for £5 (about $8.50) and it's pretty good for the money.
I started with this once I opened the box.
The kit snaps and screws together fairly easily and is pretty detailed with fully modeled engine transmission and exhaust system. The transfer stickers caused a bit of difficulty but I got most of them fitted okay.
Overall it's a great model with only the lights being hard to align out of the box (a smooth file and some glue should fix that).
The paint looks great overall and isn't orange peeled or too thin like a lot of cheaper models.
The interior is above average for the price point too, with a fully modelled fire extinguisher and metal effect pedals. There was meant to be a Lamborghini badge on the dash but I managed to lose it.
Overall it's a great model and I doubt I could beat it for this kind of money. They had a Reventon too which a friend picked up.
