What do I think? A lot comes to mind, but the most telling is I wouldn't touch that 355. Nitrous, front lip, painted wheels, and wing all make me cringe. Someone out there likes it but it is not me.
I'd personally not want a car that had been nitroed. Maybe he did only use the juice 5 times, but does a guy who wanted his 355 to be a red-light racer sound like the kind of guy who treated the car properly? Burnouts, donuts? I guess I'm saying it might be the best 355 out there, but there are too many others to consider before this one, jmo.
"This car is easily worth over $75K!!" I guess this is the part that makes me feel like he is doing me a favor and selling it to me for the low, low price of $55K with a melted engine. SOLD!
