Out of curiosity, what's wrong with the used Ioniq EV I posted for $20K? Is it less desirable from a driving standpoint than a Volt?
I'd spend the cash and get a new Model 3 like I originally said. It'll cover the EV desire, but it's also just a very good driving sedan, so you won't be missing your GTI too much (and there are no roll bars to slam your head against). Or better yet, step up to the LR used one you found, pay the $2K for the performance upgrade, and you'll have a great car for some time to come.
