Any track time is better than no track time. Biggest thing everyone learns quickly is that there is no replacement for seat time no matter where you're at. However, we don't currently race at Harris Hill, so any time spent there right now shouldn't be done worrying about making the car faster, but rather making the driver more comfortable on track. I would say prioritize the tracks we do race on to the top of the list when signing up for HPDEs, but if you have the time and opportunity, don't pass up Harris Hill especially if its a good deal.
Keep doing DEs in your AutoX car. If you are truly motivated to go W2W racing, you don't want to waste time trying to sell it then get a racer. At your first couple of events, you shouldn't be able to realize the difference in performance since you'll be well slower than the race pace we keep in class.
One more hint, try talking to SVO Chuck about whats for sale in the RM region. We get a lot of traffic between Texas and Rocky Mountain since they are both run by the same people. This could lead to a transporter coming down here from Colorado with extra space that could bring a car down if you found one you like. Last I heard, they still have 3 for sale up there. Just a recommendation.
