Good idea! Means you can get deeper into converting the Z into a track car and we can run together with similar cars!
I've heard good things about Tahoes as DD's and tow vehicles... not surprised to hear that you miss it vs the Expedition
CRZ sounds sensible... sounds like you're looking for a reliable DD with warranty? are you going to keep it stock?
I'm seriously thinking about getting the Ruckus as an alternative means of transportation... would that be enough for you? do you have a short commute on low speed roads? or do you have to get on highways?
