Convert Carbon to a Carbon GT?

First post! Been looking at esk8s for about a month now. Use my Goped ESR750 and ESR750H a bit, but think I'd like to convert. Found a used single motor Carbon in good shape for $700. I think that's high, but thinking about making an offer. Any feedback on the single motor vs. the current GT? I was wondering if I got this thing cheap enough if I could basically covert it to a GT for a reasonable cost. Anyone tried that?

 

if u want to convert to gt, u have to change all the electronic parts.. besides that a single motor carbon using different truck than a new carbon gt..if i were u, i straight away buy carbon gt, less headache.
