Welcome!
Are you sure you're only 16? 'cuz you sound more mature than me... and I'm.. like... thrice your age...
I bought my first Spider when I was 17, but it was my 4th car (not counting the crappy stuff my parents owned that I drove) so I already had some stuff to compare its' ownership to.
Needless to say, it was great owning a Spider, 'cuz I'm still addicted.
Shoot your questions out... we'll do everything we can to help out.
And someday you need to start a thread over in the Non-Fiat Related section about your Coronet build. that'd be fun to watch too. I also have a long history of muscle-car ownership, and even some racing, as do several others on this forum.
I'm no Boy-Racer..... but if I can't take every on-ramp at TWICE the posted limit.... I'm a total failure!
