I really like the 4C... what a nice looking, cool car. But there are two things that would ultimately keep me from buying one:
1. Size: I seriously wonder if I could fit. I came from an NC Miata, which I found to be roomy enough to keep me happy on a 4 hour drive. But being 6'7", 240lbs... I have a feeling the 4C is a wee bit too small. Sadly.
2. Reliability: It's an Alfa. Alfas have never been known to be reliable cars. Maybe they've changed in the last 10 years? (I'll admit, I don't follow them closely). Obviously the 4C wouldn't be a daily driver, but there's something to be said about reliability and knowing I can go on a 1000km adventure without worrying if I'll make it back. Then again, the Z with it's horrendous CSC that can leave a guy stranded in a hurry isn't exactly the epitome of reliability either
I'd be curious to see what the 5 year ownership costs eventually are for a 4C. I mean, as pointed out, it is rather simplistic... there isn't a ton to break on it (which is pretty awesome!!). But a Ferrari sourced DCT spells $$$$$$ to me. Everything else Alfa spells $$$$$ to me.
