I have come across a bmx that was trashed, it looks like a good quality bike and I would like to restore it and wanted to find out if it's worth restoring or not, it still has stickers on it which says DEVILLE CYCLE on the front of the frame and on the it says TECHNIC PRECISION and NO-MERCY, it also has a serial number on the bottom of the frame which starts with GC, but I cannot find any info or pictures of this bike, it would be great if anyone can give me some info about it.
I don't know if you're still planning on restoring that BMX, but what I can tell you is that I have that exact same bike. I have had mine since brand new and brought it in 1999. I don't think it has much value so to speak, but it's been put together to compete with Mongoose. Mine has blue chrome parts rather than the purple/pink yours has. Does your chain gear sprocket say 'CD Compact Disk'?
